a) Kate Middleton is very English. Not a Welshman or Irishman to be seen, one Scottish great-great-grandfather. And you have to go back 10 generations to find Gaston Martineau, a surgeon who fled France in 1685 (presumably a Protestant threatened by the Edict of Fontainebleau), and his wife Marie Pierre. The Goldsmith connections don't appear to be Jewish (5 generations married in church, apparently) - in the 1700s they're Kentish carpenters.
b) social mobility
The background of each of Kate Middleton's great-great-grandparents, as far as is currently known, can be summarized as follows:
- Middleton - Tradesmen in Yorkshire rising to professionals (attorneys)
- Asquith - Tradesmen in Yorkshire
- Lupton - Background of his grandparents:
- Lupton - Tradesmen in Leeds
- Darnton - Tradesmen in Leeds
- Greenhow - Professionals from Yorkshire
- Martineau - Clergymen and professionals from Norfolk and Northumberland
- Davis - Clergymen and professionals from Worcestershire, Gloucestershire, Warwickshire, and elsewhere in western England
- Glassborow - Tradesmen from Surrey
- Elliott - Tradesmen from Surrey
- Robison - Clerks from Scotland
- Gee - "Gentlemen" descending to tradesmen
- Goldsmith - Labourers from Kent and Hertfordshire
- Dorsett - Labourers in London
- Chandler - Labourers from Gloucestershire and Worcestershire, rising to tradesmen
- White - Tradesmen from Somersetshire and Buckinghamshire
- Harrison - Miners in Northumberland and Durham
- Hill - Mariners in Durham, later tradesmen
- Temple - Miners in Yorkshire and Norfolk
- Myers - Agricultural labourers in Yorkshire
Around 50% middling men and women (the Luptons were a well-known Leeds family - there's a university hall of residence named after one of them), 50% working people. One jailbird, Edward Glassborough, an insurance company messenger - wonder what he was in for ?
c) the seeming total absence of bastardy. Everyone has two parents, and they are married to each other. So much for the historical revisionists.
d) I see one of the Harrison miners married a Jane Liddle. Hopefully there's a Rod Liddle link. What has apparently been established are links to Guy Ritchie, to her husband Prince William, and to various other aristocrats*. The native population of these islands being a partially inbred extended family**, there are bound to be links. Go back 10 generations and you have 2 to the power 10 i.e. 1024 ancestors, which takes you back to the 1600s. Go back another 10 generations, to the 1300s, and you have over a million forebears. There are around 50 million native Brits in the UK, each with getting on for a million forebears in the 1300s - but there were less than 10 million Brits around in the fourteenth century. Obviously we*** have an awful lot of ancestry in common.
* as you go back and records are scarcer, those for whom records ARE available tend to be the great and the good, so a tree gets biased towards higher classes as you go back.
** the inbreeding being generally inside the distinct populations of England, Ireland, Scotland and Wales, at least until the greater mobility of the eighteenth and nineteenth centuries.
*** those who are not, like myself, the son of an immigrant father. That's most of the native Brits.
