Hello! My Great-Great Grandfather, Dr. Henry LaTour immigrated from France in 1851 and arrived in SF. I have little information on him in France but I do know that he was born 10/25/1820 in France and that he married Eugenia Chevalier(born 12/4/1824) in France. I am really wanting to know everything I can prior to 1851 and if anyone has information on him, or his wife,I would really appreciate it!!
