This is very interesting...
The Jansens and The Hardings meet again :)
Warren Dick Harding b 30 Nov 1931 L.A., CA
Lucille Delores Jansen 24 July 1929 Manning, IA
they married in Medford, OR, 15 Feb 1955.
(I have Janssens in my family too) Some of the Janssen's coming to the US, dropped the 2nd "S". Some made it an "N"
Jannsen...I also have Jensen & Janshen's, same family, so be careful to include possibilities...ever look at the "original" handwritten censuses?
