I'm looking for Anna Mechtildes Janssen, born in Sittard (NL) in 1789. She is the daughter of Stephane Janssen and Maria Cornelia Tunners. She married Hilaire Brisson in Treveray (France) on 20/12/1815. Stephane Janssen made a procuration on 30/12/1814 at a notary's in Sittard to allow his daughter to marry.
Please contact me if you have information about this Janssen family.
I'm also interested about how to get information about this family. How can I get a birth certificate from Sittard city? Where can I find the procuration done at the notary's?
