WOW Gaby, I am overwehlmed with everything you found for me
THANK YOU. The Christine Burbach in my family is the one who married Heinrich Hausmann in Dormagen.
THANK YOU so very much for your help, especially with Johann Klett. He was the only one on the Klett side that I could not find, with the exception of census records. In 1862 it was he and his wife Maria and their 6 children that came back over.
Through the census records I was able to get the addresses to where they lived in NYC and a friend and I drove around taking pictures of all the buildings. Most of the buildings were still there to my surprise.
