I just made an amazing discovery! I went to the rootsweb site and typed in Emile Lepine. I found Emile Joseph Lepine born 9/11/1850. That is the correct year of birth and I feel sure that this is the correct person. He has three siblings, Victor [bn 1839], Charlotte [bn 1843] and Jean Baptiste Augustin. I feel sure that the Emile who came to LA named his kids after his deceased siblings. Jean Baptiste died in Belgium after Emile died here in 1925.
This Emile Joseph Lepine was born at Familleureux, Hainaut, Wallonnie, Belgium. His parents are Augustin Joseph Lepine and Victoire Linard. There is more info on them and a few more generations on the Linard line.
Go to the site and check it out! There is an e-mail address for the submitter and I'm pretty sure that he is in Belgium!
Hope you find your husband's relatives in Belgium!
