How about:
Victoria Melita and Erna Ludwig von Hesse -
Princess Alice mother of Ludwig and Prince Alfred father of VM were siblings.
Marina nad George Duke of Kent weren't quite close cousins?

[CarolinaLandgrave]

Were not George IV and Queen Carolina 1st cousins? Didnt the Duke of Cumberland (who became King of Hanover) marry a Mecklenburg 1st cousin (had already "disposed" of two husbands).
Adolphus and Augusta Cambridge were 2nd/2nd Once Removed, correct?

[CarolinaLandgrave]

Princess Augusta of Cambridge and her husband, the Grand Duke of Mecklenburg-Strelitz were 1st cousins through the Hesse-Cassel family - but were kin also as descendants of George II ( I think)

Russo, if you please.
We may be getting some whiskers in our old age but we're not entirely manly--yet!
Marrying cousins was quite common, and we all know QV popped out a huge brood, but I can say I'm happy it is stopping and that I agree with Prince Philip when Diana injected new genes into the line!

[CarolinaLandgrave]

My Apologies, Russo...
and yes - marrying of cousins was quite common....
two of my great grandparents were double first cousins! hahaha

But in seriousness, the British royal family - had no time at all with the Hapsburgs. The uncle/niece marriages were just gross and cruel.

The royals married cousins more than us common folk, Mr Landgrave. Had to keep up the royal alliances you know.

[EmpressRouge]

Back in the day when transportation wasn't as advanced, even common folk had a high chance of marrying a cousin, alliance or no alliance. If you lived in a small isolated village (or even a group of towns), you would eventually run of out non-relatives to marry. And given infant mortality, the populations were not as large as they are now. Add to that people did not associate outside of their class, and your pool of potential partners dwindled down even more.

[CarolinaLandgrave]

Empress R - thats exactly what my two grandmothers said - you married the people you saw at church or associated with in the community - and after a generation or two, they were likely related to you. And much like the nobles and royals of Europe (on a smaller scale, per say), the best way to hold on to your property is to marry a family member.

Unfortunately all of that inbreeding, while useful for treaties, had a rather disasterous effect on many royal houses. From hemophilia, the hapsburg 'lip', to the many mentally deficient rulers/heirs over the centuries. Combine the inbreeding with the rampant and untreated venereal diseases in the old days and you've got quite a 'Prince'.

[CarolinaLandgrave]

I know! The Hapsburgs especially - its a wonder that any of them could carry out the basic functions of human day to day life!

Most hemophilia is not affected by inbreeding. It takes only one defective gene passed from mother to son to make a hemophiliac. Now if a hemophiliac married his first cousin, a hemophilia-carrier, they could possibly have a hemophiliac daughter but that's so rare, I've never heard of such a case.

The Hapsburg lip wasn't a genetic defect, per se, but a strong dominant facial feature that was passed down from generation to generation. The Hapsburgs courted disaster by marrying uncles to nieces and that causes a whole load of genetic problems.

From what I've read, the risk of birth defects of a child born in a first-cousin marriage is about the same as a woman giving birth to her first child at 40, about a 6% higher chance than the normal population. But marriages from any relations closer than that can cause severe birth defects.
