Mary Irene Cox, nee Joyce (from headstone) was b 9/3/1900 in Melbourne Australia. Her father was John Marshall Joyce who d in South Africa on 9/12/1924. Listed on the probate record is Mary Irene McLaughlin (born Joyce). Presumably this means at that time she was married to Frank McLaughlin and by 3/6/1934 was married to Victor Gwilliam Cox when their son was born. This still leaves the question of what happened to Victor Gwilliam. I have identified the sons marriage will research that a little more but that is not for Rootschat as both potentially living.
