A few days ago, a Johnny Driesen from Belgium posted a reply to one of my posts. He gave the information that Emile Lepine was born in Paris and was the son of Jules Lepine [bn Paris] and Rosalie Band. He is listed on that Antwerp Police immigration document that I wrote about earlier [year of 1870]. Johnny will search the "Antwerp population" [I suppose that is a census]. The charge would be 15 euros. If you are interested, I can give you his e-mail address.
I will look in the Paris records to see what I can find.
