I'm afraid I can't answer your question, but I wondered if you could help me with a question of my own. Is your grandfather, Alexander Defran DeVille Jr., the son of Alexander Defran DeVille and Augustine Gradeni? If so, your grandfather is my great-great grand uncle. His sister, Clementine, is my great-great grandmother. I've just begun my genealogy search, and this family has been the focal point of my investigation thus far because publicly available information on them seems so sketchy and conflicting. It's only through family memories and documentation that I've begun putting the pieces together. Thanks for your time and attention!
