I am from Kalafut lineage, which is confirmed to be from the Village of Maniowy in the former Spis County of the Austrian-Hungarian province of Galicia. It is now in the very south of Poland, with many Kalafut's still there.
So my Kalafut's are Slovaks (well, now Polish).
My great grandfather John Kalafut was the son of a Frank or Francisek. I don't know if John had any siblings -so would be interested to find out. John came here in 1911, and settled with wife Antonia in Passaic NJ then later Whippany NJ.
