I believe my Grandfather IS the same Gavin (Guy) Hamilton. He was married before my Grandmother and had two children, a Daughter Margeurite and a Son Robert. Grandpa and my Grandmother, Lillian, had ten children, my Father was the eldest. Sadly, he passed away in 2009. Grandpa DID live in Moose Jaw where I believe he met my Grandmother. They came to British Columbia when my Father was young. Grandpa was a musician, playing in and organizing bands whereever he was. One of my fondest memories is of Grandpa playing the trumpet......in the barn! I would very much like to correspond with you more to exchange information.
