Royal Descent - Proving Royal Descent

Proving Royal Descent

Royal descent is easier to prove than descent from less notable ancestors, because genealogies and public records are typically fuller, better known and well preserved in the case of royal descent than in the case of descent from common people. It is only since the 20th century that family history has been an interest pursued by people outside the upper classes. Hence, the continuous lines of descent from royal ancestors are much better researched and established than those from other ancestors. Until the parish record system in the 16th century, and civil registration in the 19th century, family records are fuller for landowners than for ordinary people.

Between 1903 and 1911, the Marquis de Ruvigny published volumes entitled The Blood Royal of Britain which attempted to name all the then-living descendants of Edward III of England. He gave up the exercise after publishing the names of about 40,000 living people, but his own estimate was that the total of those of royal descent who could be proved and named if he completed his work at that time was 100,000 people. His work, however, was heavily dependent upon those whose names were readily ascertainable from works of genealogical reference, such as Peerages and Burke's Landed Gentry.

The English geneticist Professor Stephen Jones estimates that 25% of the British population is descended from the Plantagenets.

The phrase "English descent" does not, of course, mean purely English descent: As soon as an immigrant family marries into an indigenous family, it acquires all the ancestors of its indigenous parent, and is therefore no less likely to be able to claim a royal descent than a non-immigrant family.
