I just found out from a cousin, whom I've just met because of Wikitree, that my g g g grandmother, reports that her g grandmother was a Spanish noblewoman, who married a commoner and was disowned. Apparently the name Isabella was used in our family because of that. My g g g grandmother in question is Moore-40430, but unfortunately I can't get back much further to really see if there is anything to the claim. I'm not really seeking direct help pushing the tree back further, although it is always welcome. But I'm wondering where I can find Spanish noble trees to search through, in hopes I can find a connection. The rest of my family are all British so far, and I'm well aware of most sources for Britain. But this is a new direction for me. Thank you.
