I had posted here a while back about my great-grandparents, and have made some significant headway since then. I figured I would write and share what I found.
IF your Kalafut's are from the same place mine are, then they are from Southern Poland, an area formerly known as Spis County. Chnaces are that they are from the same place, as the last name is from a specific area and people were born and died in the same town - and in their lifetime only went a few miles from home.
My great-granfather, John Kalafut, was from Maniowy - which was located in Slovakia, then Austria, then Austria Hungary, then Poland. The village was flooded by the Polish Government in the 70's to make way for a resevoir, and was moved up the hill.
John's father was Frank - or Francisek. If you are looking for your ancesrtal hometown, look up your great-grandfather Andrew's passenger manifest at Eliis Island.org . The older manifests (1900-1920) tell you their nearest relative at home, their destination (Passiac, NYC, ...) and their home country and hometown. Also, if Andrew was a citizen, look up his naturalization poapers at the courthouse - that's how I found my g-grandfather's hometown.
Anyway, hope to learn more. Hope to find another Maniowy-ite.
