Paul LeMaitre

I know you folks all seem to be checking out the 18th century, but I'm having problems in the 20th!I'm looking for my grandfather, Paul Dominique LeMaitre - born in 1871 in Compiegne and married to a woman named Deydier (sp?).He moved to East St. Louis, IL around 1891?, and eventually to St. Louis, MO, where he married my grandmother Alice Thorp and had my father, Robert Lee LeMaitre in 1919.By his first wife he had two kids, Leon Paul LeMaitre and Pauline LeMaitre.Unfortunately, grandpere is my wall.His father may have been also named Paul, and his mother Desiree Chapelle, but other than that (places, dates, parents, etc.) I am at a loss...

Would any of you know about my family?

Thanks!

John LeMaitre
