My great-grandfather was Juan Cuevas Pol. I believe either he or his father was banned from the family and disinherited for marrying a poor woman.
My grandmother is now 90, her name is Gregoria.
My mother says she doesn't remember ever meeting any of my great, great "relatives".
The Cuevas on my side are all quite petite and fair skinned.
Does any of this sound familiar to anyone in your family?
