Alphonso XII's inbreeding

Legg inn av James Dow Allen » 04 nov 2004 06:46:39

Although Alphonso XII King of Spain wasn't medieval,
I hope s.g.m'ers will forgive me for posting his pedigree.
(After all, he did have medieval ancestors!)

I hope the pedigree is correct; please inform me if not.

Alphonso XII's parents were double cousins which by itself
would give him a WIC (Wright's Inbreeding Coefficient) of
0.125. However when other connections are considered he
gets a WIC of .25, as much as for the offspring of siblings.
This is the highest WIC of anyone in my database, except for
those who actually were the offspring of siblings.

From the following partial pedigree a WIC of .234 can be
computed for Alphonso XII. Only two of Alphonso's great
great grandparents are missing from the diagram; these
are Philip's wife (who was Philip's own 1st cousin once
removed) and Ferdinand I's wife (who was Ferdinand's own
2nd cousin once removed). These and other inbreedings
bring the WIC up to .250.

If you want to try your hand at computing the WIC manually
in this complicated pedigree, check your work (or check mine)
with the relevant path lengths I've shown below.

Dear James,

First, there is an offical family tree and there is an un-official
one----the un-official one removes lots of the inbreeding. But why do you
call Marie Amelie de Wettin by that name?
She had a very distant ancestor who build the castle of Wettin but that
doesn't make it her surname/family name or title. She was a Princess of
Saxony.
Best wishes

I don't know why anyone would want to do a laborious manual
calculation when there is a fine, fast program to do it available at
http://www.tenset.co.uk/fspeed/
We've (they've) come a long way since 1998-99 when Tom Fettes was
struggling
to write a program.
This is OT, as far as Alfonso XII is involved, but going back to his
XVI century Habsburg ancestry will bring it back on topic.

My preferred claimant to the French throne, the Count of Paris, is
also quite inbreed. His mother was an Orleans princess, as was his
father's mother and his father's mother, just for starters.

She was D. Izabel de Orléans e Bragança, a Brazilian
princess. She used to preside over the meetings of our
College of Genealogists in Rio.
