Not that I know of but then I don't have any real genealogy. Grandfather from the province of Leon, one grandmother was from near Pamplona so Spanish Basque. The other grandmother was from Barcelona.
No blindness in the family ... other than the DDs when they figure "If I don't see it I don't have to deal with it".
Well that's a good thing.
Have you thought about doing a DNA test to find more info on your family?
