I recently found out my mother's maiden name is not Spanish, it's French but the spelling was changed to look more Spanish because my ancestor was in the French army that invaded Mexico to try and expand their empire in the 1860s. Apparently he deserted the army when they lost and ended up marrying a Spanish woman there in Mexcio. There was all kinds of stories before about them being Basque or something but I did the research into the name and found out it's origin was French. I am now part frog. History is fun.
