Zuger from Hohenhaslach, Württemberg
Diane, when my husband and I moved to Berks County, PA, from New York State, we were surprised to discover that his mother had relatives (related via Germany) in Berks County (not with the surname Zueger or Zuger). My husband also has Zuger ancestors (again via his mother) from Hohenhaslach, Württemberg. I have copies of some of the early records (1600's), and there does not appear to be an umlaut over the letter "u" in the surname, although perhaps in later records there was. Someone submitted the surname as Zuegler to the I.G.I. I would not be so quick to assume that the surname was Ziegler, etc. I would check out the Zugler's first.
