Hello,
Henry Francis Latour and Eugenia Chevalier were my grandmother's paternal grandparents. My grandmother was Leota Iris Latour Dillian; her father was Henry F. Latour and her mother was Olive Pate.
I found somewhere that Eugenia was from Oise, Picardie France, but I have not been able to find out when she and her husband Henry (Henri Francois?)
were married or immigrated.
I am happy to see your post!
