Hi Sandra,
This is what I have got on his family his father was william Hamilton born 1896 in wishaw,Lanarkshire his mother Margaret Robertson Paterson was born 1897 in West Benhar Lanarkshire. His father was a police Constable in Scotland then the family moved to Moosejaw,Canada in 1927.
his siblings are....
Helen Sneddon Hamilton born 1920 Holytown,Lanarkshire died 2007 Nanaimo,Canada married a Thomas Price.
Elizabeth Whitelaw Hamilton b1923 Holytown,Lanarkshire d2010 in Kelowaia,Canada married Willard Legault.
John Paterson Hamilton b 1924 Chryston,Lanarkshire d 2006 in Naniamo,Canada not married.
Margaret Paterson Hamilton b1929 Swift current Canada d 1980 Vancouver married Douglaa Roger's.
William Hamilton born 29 Dec 1918 Harthill,Lanarkshire he married Moria Eleanor Reilly on the 31 Dec 1942 and had a daughter Arleen Lynn Hamilton B 1944.
I had spoken to Moira a few years back by telephone from my home in Scotland and what she said was that they were divorce divorced shortly after their daughter was born and he disappeared. I then found in 1953 on the Border crossing Canada USA document. And it say that he has a son William Hamilton staying at 119 19th N.E Calgary Alberta. The last record I found for him was Nevada Death Index in 1985.
Hope this helps.
