Surnames: Longwell, Dupy Classification: Query Message Board URL: http://boards.ancestry.com/mbexec/msg/rw/Ig.2ADI/1162 Message Board Post: Looking for information on the Longwell family of Jersey County, Illinois as it relates to Mary E. Longwell, born in 1848 and died June 11, 1867, she is buried in Oak Grove Cemetery. She married Lafayette Dupy on January 1, 1867 in Jersey County, Illinois. I am trying to determine if this Lafayette Dupy is my great grandfather.
