I recently found some information regarding my ancestor Frederick DuJardin (Fredericus Adolphus DuJardin)b. 5 Aug 1836 in Ghent, Belgium. His mother was Joanna Josepha DuJardin b. 1816 Ronseval, Oost-Vlaanderen, Belgium. Father unknown at this time.
If you have DuJardin family that came from this Belgium area, I'd be interested in communicating to see if there might be a connection.
