Obviously I don't have the surname, but I'm decended from people who did--my great grandparents were both decendents of Jacques Payant dit St.Onge. Charles Santo (whose father's last name was St.Onge--Charles' name was shortened) married Rose Payant. They had three children--Lyle (c. 1902), Sylvan and Agnes(?) Santo. Lyle married Margaret Hannon and had three children as well--Joan (1926), Donald and Charles Santo. Of these, only Joan and Charles are alive today.
