See http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0005174 for an interesting article about the level of inbreeding amongst the kings of the Spanish Habsburg dynasty. An interesting project would be to document these people here. Thurstan 03:04, 16 April 2009 (UTC)

Agreed. We have a distinctive Anglo-Saxon bias. It would be even cooler if we would compute inbreeding coefficients ourselves. Rtol 05:01, 16 April 2009 (UTC)
