I am Rosalee (Hanzsche) Rodkey. I am not sure there is any connection with my direct family but it is interesting that my ancestor John Godfrey Hanzsche came to the U.S. in the 1830s from Hanover Germany. He was a book printer and came to Baltimore Maryland where he married Henrietta Charlotte Hall. They then moved to Cincinnati Ohio.
The name is not that common and although some branches of the family have dropped the "z" it maybe that there is some connection.
