I'm helping my best friend trace his family tree, but unfortunately we have already hit a brick wall. All four of his grandparents died before he was born and he doesn't know their names. His parents are Maurice Rizk and Sandra Maroun both born in Beirut Lebanon. Sandra was born 01 Jun 1942. I don't know Maurice's birthdate. Maurice and Sanra emigrated to Sydney, Australia, where my friend lives. Can anyone help me fill in the blanks?
