Am also descended from Henry Christina Conrady. They were my grandmother, Winnie Conrady's great grandparents. Henry was actually b. 7 Sep 1809 in Berlin, and Christina Zugschwerdt Conrady was b. 6 Mar 1832 in Hessen-Darmstadt. I have some information on the Zugschwerdt family. Pse email me at mamie1866@aol.com, as I check these boards infrequently.
