I am searching for some information about my great uncle that came to visit my grandmother near St. Catharines, Ontario, Canada in approximately 1922. My grandmother Isabel Leslie and Uncle John were twins born in County Antrim, Belfast, Ireland in 1887. According to my older cousins, after he left here he supposedly left to go to Australia, but we are not sure. He was never heard from again. I have found info on his coming to Canada via a passenger list, but have not seen anything else showing his leaving via a ship from Canada. Perhaps he went to visit relatives in the US as his mother had a brother in America or went back to Ireland.Does anyone have any relatives that might fit into this description? Thanks.
