My grgrgrgrandfather was John Allen.He married Catherine Rouguen (French spelling, as she lived in French Louisiana but she was Irish, so I imagine the spelling should have been Rougen, Rogan, etc.). These Allens lived in Iberville and Point Coupee Parishes, La. Names of some of John and Catherine's sons: Lewis, Albert, Sylvester, Joseph( my grgrgrandfather). I can't remember the names of their other children, and don't presently have that info accessible. This John Allen was from Ohio.
