I am researching for the Wolf family, the Hafner Family and the Haas Family.I have very little information to go on at this point..Update 10/15/98...I now know that my Great Grandfather Wolf's given name was Jakob and his wife's name was Mary Bury.
I know the Wolf family came from, I believe, the Pennsylvania or Pittsburg area and some members now reside in Michigan.
My Grandmother's surname was Hoffer and she came from Hungary, and I believe she had a sister by the name of Veronika.
The Hafner family I believe came from Ohio or Indiana.
The Haas family I believe last known area was Kansas and/or Missouri.
