There COULD be a connection as many times people came over with other family members. I have not yet found when my Kazimier came over from Poland, but I know it was before his wife Frances and 2 of his children did in 1899-1900. Considering that you have the names Casimer and Victoria lead me to believe there MAY be a connection somewhere here. I think if I could find my ancestor on a passenger list, I could find out if he came with a brother or sister.
Let's keep each other posted, ok?
