I'm searching for the family tree info related to a Marie Jani married to Roman Weinpel. There's likely a Frank Jani somewhere in the family as he witnessed the marriage of Charles Weinpel and Anna Ripper, Charles being the son of Marie Jani and Roman Weinpel. Charles was born 6/6/1877, emigrated 1902 from Hungary-Austria, settling in Passaic, NJ area, and died 7/26/1924. Marie Jani may have never come to the U.S.
There are some Jani family members that include a Frank Jani that lived in the Passaic area but I don't know if they are related. There's a Paul Jani married to Theresa with children Geo and Joseph. There's a Frank Jani married to Mary with children Mary, Frank and Joseph.
Let me know if you think this might be a connection.
