When you hear the names, Mary and Joseph, they aren’t names you’d probably associate with a Jewish couple. However, according to the 1901 census, there were 6 Jewish women called Mary in Cork. Joseph is a more common Hebrew name (Yosef) so it isn’t that surprising to find 18 of them in Cork. Mary and Joseph Spiro lived in number 74 Hibernia Buildings. Both of them came from Russia and it’s unlikely either used these names back there. They had seven children according to the 1901 census. For the record, none of them were called Jesus.
