I can trace my family tree to Feith in Hungary back to around 1880's, south of Budapest area (Belecska, Szentgal) They came to Wisconsin, USA around 1910 (some in Schofield, WI...others near Milwaukee). Names would have been Janos Feith or Gyorgy Feith.
I'm glad to hear from any Feith with similar fam tree.
cheers,
John Feith
