This reporter wrote about this disease among the FLDS back in late 2005.
you’d think that if I were to use a semi-obscure reference I’d at least try and spell the thing correctly. Grrrr....
Take a look at http://www.thepeerage.com/ and navigate around. In particular, check out the Habsburgs, as well as the descendants of Queen Victoria and Prince Albert. Most entries have a number that denotes the subject “Consanguinity Index,” where a higher number indicates more inbreeding. There is also a feature called the “Pop-up Pedigree,” which displays the subject’s parents and grandparents. Start going backwards from those, and the level of inbreeding will boggle your mind.
