The Doorway of Rossdhu

John M’Arthor, the McCarter Line, and the Ancestors Who Refused to Be Forgotten

By Tiffany McCarter Evans — The Lennox Chronicles / The Lennox Ark

In 2024, I walked through the old doorway of Rossdhu Castle with my 12-year-old niece.

I did not know then what I know now.

I knew Rossdhu mattered. I knew the Colquhouns of Luss belonged to that land. I knew my McCarter Y-DNA had been pulling me back toward the old Colquhoun and Kilpatrick bloodline. But I did not yet know that one of my own ancestors had already left his name there.

At the time, I only knew what I felt.

Some places do that to you. They catch you before the records do. You stand there thinking you are looking at a ruin, a wall, a doorway, a pretty bit of old Scotland. Then something in your chest says, no, this is more than that.

That was Rossdhu for me.

The later manor house was beautiful. Grand. Polished. The kind of place people stop to photograph because it looks important.

But that was not where I felt it.

I felt it at the old castle.

At the broken stone wall.
At the ivy.
At the little arched doorway still standing after centuries of weather, inheritance, loss, and forgetting.

That doorway stayed with me.

Now I know why.

In Fraser’s Chiefs of Colquhoun, on 10 June 1676, at Rossdoe, a man named John M’Arthor appears as servitor and witness to Dame Margaret Baillie, Lady Luss. He signs as J. M°Arthoure, witness.

That man was not random.

That man was my John.

John McArthur / MacArtair / M’Arthor was born in 1654 in Gargunnock, son of Donald McKertur / MacArtair and Agnes McKinlay. He was the grandfather of Moses McCarter Sr., my 5th-great-grandfather.

That makes John my 7th-great-grandfather.

And there he is, about 21 years old, old enough to stand as a legal adult male, appearing in the Rossdhu household world of the Colquhouns of Luss.

Not in a vague tradition.
Not in a family story repeated with no paper behind it.
In a record.

At Rossdhu.

The old castle world.

That part matters to me. Fraser makes clear that the later house was not the original heart of Rossdhu. The old castle came first. Those surviving stones are not just decoration beside a newer estate house. They are the remains of the world my ancestor would have known.

So when I say I felt connected to the old castle and not the manor house, that is not me being dramatic.

That was my bloodline pointing at the right stones before my research caught up.

I had walked through that doorway with my niece before I knew John was there.

That still stops me.

Because genealogy is not just names and dates. Not when you do it long enough. Not when you have held wills in your hands, followed land records across counties, matched DNA branches, tracked surname changes, and sat with the dead long enough that they stop feeling dead.

Records are not dead paper.

They are proof that someone lived.

John M’Arthor lived.

He stood in that world. He served in that household orbit. He witnessed. He signed. His name survived.

And that one record tells me something important: the Gargunnock MacArtair/McCarter line was not disconnected from the Colquhouns of Luss in the 1600s.

They still knew.

Maybe not as chiefs. Maybe not as lairds. But they were not nobodies drifting around Scotland with no connection to the old family network.

John was close enough to be trusted.

Close enough to witness.

Close enough to be named.

That is the smoking gun for me.

My Y-DNA had already pointed toward the older Colquhoun/Kilpatrick paternal field. My McCarter branch sits downstream in the E-BY5776 line, part of the MacArtair/McCarter branch I have been rebuilding through records, DNA, land, naming patterns, and witness lists.

DNA pointed the way.

But John M’Arthor at Rossdhu gave the DNA a place to stand.

A man.
A name.
A date.
A place.
A doorway.

This is my life’s work.

Not because I need a grand story. Not because I am trying to borrow someone else’s history. Not because I want a pretty pedigree to hang on the wall.

Because these people lived.

They had names before history forgot them. They had mothers and fathers. They had children. They stood in rooms. They walked through doors. They signed papers. They served households. They crossed oceans. They buried their dead. They changed names. They survived long enough for me to find them.

And we only die if we are forgotten.

So I am saying their names again.

Donald McKertur / MacArtair, my 8th-great-grandfather.
John McArthur / MacArtair / M’Arthor, my 7th-great-grandfather.
Thomas McArthur / McCarter, my 6th-great-grandfather.
Moses McCarter Sr., my 5th-great-grandfather.
James Leander McCarter.
Robert Alexander Bates McCarter.

And all the sons, daughters, wives, widows, orphans, cousins, and descendants who carried the line forward.

The deeper medieval bridge is still being rebuilt. Darleith. Ardencaple. Arthur Beag. The old Colquhoun cadet world. I will not claim what the records have not yet proven.

But I will not shrink what this record does prove.

My ancestor was there.

At Rossdhu.

In 1676.

And in 2024, before I knew any of this, I walked through that old doorway with my niece.

I thought I was showing her a castle.

Now I know I was walking her through the doorway of our own family’s recovered story.

That is why I do this.

That is why I dig through charters, wills, land records, DNA results, forgotten witness lists, parish entries, old books, and courthouse papers no one else thought to look for.

Somebody has to remember them.

Somebody has to bring them back into the light.

And apparently, that somebody is me.

The past is not silent.

We just have to listen.

And I am listening.

Archive.org: One of the Best Free Tools for Scottish Genealogy Research

One of the biggest misunderstandings in Scottish genealogy is that “old” automatically means “impossible.”

That is not always true.

For medieval and early modern Scotland, some of the best records are actually preserved in old published charter books, family histories, abbey registers, church records, parliamentary records, royal charters, and land documents. Many of these books are now available for free on Archive.org, Google Books, HathiTrust, and other public digital libraries.

This is one of the ways we are building the OneTree Project.

We are not just copying online trees or chasing Ancestry hints. We are using older published source material, charters, land records, witness lists, marriages, heirs, sibling branches, and DNA evidence where testers exist. The work is slow, but it gives the tree a much stronger foundation.

The challenge? A lot of these records are in Latin, older Scots, or legal wording that makes modern eyes want to run for coffee and emotional support. So before I post many of these records publicly, I have to extract them, translate them, compare them, and then place the people into the correct family network.

That is where the real genealogy begins.

Not with a hint.

With the record.

Some of the Source Books We Use

Here are some of the books and collections readers can search for themselves on Archive.org or other public digital libraries.

Colquhoun, Luss, Lennox, and Local Family Sources

The Chiefs of Colquhoun and Their Country by Sir William Fraser
This is one of the major published works for the Colquhoun family, Luss, Dumbartonshire, and related families. Archive.org has copies of both volumes available.

The Lennox by Sir William Fraser
A key source for the Earls of Lennox, Lennox families, lands, charters, and muniments. It includes both memoir material and record evidence.

Cartularium Comitatus de Levenax
This is the chartulary of the Earldom of Lennox, covering charters from the early 13th century into the later medieval period. Some copies may be easier to access through HathiTrust or other public digital libraries rather than Archive.org.

National Scottish Record Collections

Registrum Magni Sigilli Regum Scotorum
The Register of the Great Seal of Scotland. This is a major source for royal charters, land grants, confirmations, resignations, heirs, offices, and noble families.

The Exchequer Rolls of Scotland / Rotuli Scaccarii Regum Scotorum
These contain financial and administrative records, often useful for identifying offices, lands, payments, crown activity, and named individuals.

The Acts of the Parliaments of Scotland
A major legal and political source for Scottish history, land, forfeitures, offices, parliamentary acts, and national-level records.

The Register of the Privy Council of Scotland
Especially useful for later medieval and early modern Scotland, including disputes, bonds, criminal complaints, feuds, government orders, and named family groups.

Calendar of Documents Relating to Scotland
A very important source for Scottish records preserved in English archives, especially for the Wars of Independence period and Anglo-Scottish material.

Origines Parochiales Scotiae
A major parish-by-parish source for the ecclesiastical and territorial history of Scotland. Very useful for place-based research, lands, churches, and early territorial families.

Abbey, Church, and Charter Registers

These are gold mines because abbeys recorded gifts of land, confirmations, witnesses, disputes, churches, tithes, and family relationships.

Registrum Episcopatus Glasguensis
The Register of the Bishopric of Glasgow. This includes medieval ecclesiastical charters and is especially important for western and central Scotland.

Liber Cartarum Sancte Crucis
The charters of Holyrood Abbey, also known as the Abbey of the Holy Cross near Edinburgh.

Liber Sancte Marie de Melros
The register of Melrose Abbey, largely Latin, with important medieval charter material.

Liber S. Marie de Dryburgh
The register of Dryburgh Abbey, another important medieval charter collection.

Liber S. Marie de Calchou
The register of Kelso Abbey, covering charters from 1113–1567.

Registrum Monasterii S. Marie de Cambuskenneth
The register of Cambuskenneth Abbey, covering material from 1147–1535.

Liber S. Thome de Aberbrothoc / Registrum de Aberbrothoc
The register of Arbroath Abbey. Useful for medieval land, church, and witness records.

Registrum Episcopatus Aberdonensis
The register of the Bishopric of Aberdeen, another Latin-heavy but valuable church and charter source.

Registrum Episcopatus Moraviensis
The register of the Bishopric of Moray, useful for northern Scottish ecclesiastical and land records.

Why These Sources Matter

These books can show things that an online tree cannot:

Names of heirs
Marriage contracts
Witness lists
Land transfers
Sibling and collateral branches
Clerical relatives
Feudal superiors
Resignations and confirmations
Connections between families across generations
The movement of land from one family into another

That is why OneTree is being built from more than just direct-line genealogy. Scottish families did not exist in neat little straight lines. They were networks — brothers, sisters, cousins, witnesses, landholders, heirs, tenants, churchmen, and marriage alliances.

And yes, sometimes the clue is hiding in a Latin charter from 1225 like it has been sitting there waiting for someone stubborn enough to read it.

Spoiler: I am that stubborn.

How Readers Can Search

Go to Archive.org and search the exact title. Try both the English title and the Latin title. For example:

“The Chiefs of Colquhoun and Their Country”
“The Lennox William Fraser”
“Registrum Magni Sigilli Regum Scotorum”
“Origines Parochiales Scotiae”
“Liber Sancte Marie de Melros”
“Registrum Episcopatus Glasguensis”
“Exchequer Rolls of Scotland”
“Calendar of Documents Relating to Scotland”

Also try searching by surname, land name, parish, abbey, or Latinized spelling.

For example, Colquhoun may appear as Colquhone, Culquhoun, Kilpatrick, de Kilpatrick, Luss, or tied to lands rather than a modern surname spelling.

That is why this work takes time. But it is also why it matters.

OneTree is not just a tree. It is a working reconstruction of Scottish kinship, built from records, charters, land movement, and DNA where available.

Before anybody starts building a complaint wagon, read this first:

This graphic is a simple teaching example about ancestry, migration, and how DNA gets passed down over generations.

It is not about ranking people.
It is not about “pure bloodlines.”
It is not using gummy bear colors as literal skin color.

The colors represent ancestry examples, not human worth, identity, or fixed little boxes.

Humans have been moving, mixing, marrying, surviving, and passing down DNA for tens of thousands of years. Long before modern countries, borders, and labels existed, people followed water, food, climate, trade routes, and survival. Populations met, separated, reconnected, and mixed again. That is human history.

In this meme, the gummy bears use simplified ancestry examples like European, African, East Asian, Indigenous American/Latino, Balkan/Mediterranean, and Indigenous Australian.

Those are teaching categories, not fixed identity boxes.

The point is simple:

Each child gets about 50% of their DNA from each parent, but each parent is already carrying DNA from many earlier ancestors. So with every generation, ancestry gets shuffled, recombined, and mixed again.

That is why human ancestry does not stay in neat, tidy little boxes.

Some populations have had more regional continuity than others at different points in history, but no living population exists frozen in a glass case untouched by time. Humans have always moved. Humans have always mixed. DNA keeps the receipts.

So before anyone says:

“These groups are oversimplified.”
Yes. On purpose. It is a basic educational graphic, not a 900-page population genetics dissertation.

“Latino isn’t one DNA category.”
Correct. That is why it is used here as a simplified ancestry example, not as a single genetic category.

“Nobody is pure.”
Exactly. That is the point.

The whole message is this:

Human ancestry is layered, ancient, and mixed.
We are not neat separate boxes.
We are the result of migration, recombination, survival, and generations of people meeting other people.

This is not a “what are you” chart.

It is a visual way to show that if you go back far enough, human history is a story of movement and mixture.

And after enough generations, the family tree starts looking less like clean branches and more like somebody threw a bag of gummy bears into a wind tunnel.

Which, honestly, is probably the most accurate part.

Britain in A.D. 500 — cleaned up from an old historical map

I found an older map of Britain around A.D. 500 and decided to rework it so it was easier to read and a little prettier to look at.

And before anyone starts hollering, yes — people have been copying and redrawing old maps forever. That is literally how a lot of historical maps survived. Someone copied them, cleaned them up, relabeled them, fixed what they could, and passed them on. So I am just continuing a very old tradition, only with better tools and slightly less candle smoke.

This map shows Britain after Roman rule, when things were anything but neat and tidy.

The pink area marked Welsh represents the broader Brittonic-speaking people of Britain. On older maps, “Welsh” was often used in that wider sense, not just the modern country of Wales.

The blue areas show early English or Anglo-Saxon colonies, mostly along the east and southeast.

The green areas show Gaelic regions, including Ireland and parts of western Scotland. Northern Britain also includes the Picts and the Scots of Dál Riata.

The important thing to remember is that these were not modern borders. Nobody was standing there in A.D. 500 with a clipboard and a border checkpoint. These are approximate zones of language, settlement, influence, and power.

This was a messy, fascinating time: Britons, Picts, Gaels, Scots, and early English groups were all moving, fighting, trading, marrying, and reshaping the island.

Basically, history was doing what history always does — making a mess and leaving us to sort it out 1,500 years later.

I kept the feel of the old map but made it cleaner and easier to follow for the group.
