Royal ancestors: how to tell if you actually descend from a king
Almost everyone of European descent probably descends from Charlemagne. That is not flattery — it is what happens when you double your ancestor count every generation for forty generations in a population that kept marrying across itself. The interesting question is not whether you descend from royalty, but whether anyone can document the line that gets you there.

The short version
- The statistical claim
- Population models (Chang 1999; Rohde, Olson and Chang 2004) imply that essentially everyone of European descent descends from Charlemagne, who died in 814. It is a modelled result, not a documented one.
- Why it feels rare
- Descent and documented descent are different things. Most lines vanish into unrecorded peasantry within a few centuries.
- The usual bridge
- A gateway ancestor — a colonist with a proven line back into the nobility.
- Generations to 1066
- Roughly 30, at a generation every thirty years or so. Different lines in the same tree can easily differ by five or more.
Why 'descended from royalty' is both true and meaningless
Every generation back doubles your ancestor count. Thirty generations gives you more than a billion ancestral slots — far more people than were alive in medieval Europe. The only way to fill those slots is for the same people to occupy many of them at once, through distant cousins marrying distant cousins across centuries. Genealogists call this pedigree collapse, and it means the medieval population is ancestral to nearly all of us many times over.
So the boast is nearly always true and nearly always worthless. What actually distinguishes one family from another is evidence: an unbroken, sourced chain of parent-to-child links between you and the crowned head. That chain is what genealogical societies examine, and it is where the overwhelming majority of claimed royal descents fall apart.
The practical route runs through what genealogists call a gateway ancestor — an emigrant, usually to colonial America, whose descent from the medieval nobility has been established by documented research. If your line reaches a recognized gateway ancestor, the work above them has already been done by others. If it does not, the claim rests on you.

How to check a royal line without fooling yourself
Royal descent attracts more wishful thinking than any other claim in genealogy. These are the checks that separate a real line from a hopeful one.
- 1
Work backward from yourself
Never start at the king and work down. Start with your own parents and grandparents and move up one documented generation at a time. Every line that gets built downward from a famous person is a line waiting to be wrong.
- 2
Look for the gateway ancestor
The join usually happens at a colonial immigrant with established noble descent. If your tree reaches one, the medieval portion is already researched. If your line claims to reach a king without passing through a recognized gateway, be suspicious.
- 3
Distrust the Victorian pedigrees
A great deal of nineteenth-century published genealogy was flattering, commercially motivated, and invented. Printed lineage books are a lead to verify, never a source to cite.
- 4
Check the weak middle, not the famous end
Royal generations are exhaustively documented; your great-great-grandparents may not be. Claims break in the middle, in the ordinary generations nobody thought to prove.
Rememberkin does the mechanical part of this automatically — every line, every generation, checked at once. Run the search free.

Questions people ask
Am I descended from royalty?
If you have European ancestry, almost certainly yes in the mathematical sense — the medieval nobility is ancestral to essentially everyone of European descent alive today. Whether you can document that descent through an unbroken chain of sourced records is an entirely different question, and that is the one worth answering.
How many people are descended from Charlemagne?
Statistical models of European population mixing imply that essentially every person of European descent alive today descends from Charlemagne, who died in 814 — usually along many separate lines at once. That is a modelled conclusion, not a documented one: no published pedigree proves it for you specifically. What is rare is not the descent but a sourced path to it.
What is a gateway ancestor?
A gateway ancestor is an emigrant — most often to colonial America — whose descent from the medieval nobility has been established through documented research. They act as a bridge: if you can prove your line to the gateway ancestor, the centuries above them have already been worked out by others.
Am I related to William the Conqueror?
Very possibly, and likewise for most people with English ancestry. William died in 1087, roughly thirty generations back. The useful version of the question is whether your tree contains a documented line to one of his descendants, which is what checking your actual tree can answer.
Why do so many royal descent claims turn out to be wrong?
Two reasons. Nineteenth-century lineage books were often fabricated or wishfully assembled, and they remain in circulation. And most claims are built downward from the famous person rather than upward from the researcher, which hides the unproven generations in the middle where the real weakness lies.
