I have recently come across your website, and it is fantastic! Thanks to everyone for your hard work. My Great-Great-Great Grandfather, Corporal William Hart (1878-1918) was killed in World War I, and I have some information and images if you are interested.
William was a very blue collar, working class guy. He and his family immigrated to Canada from Scotland in 1908, and settled in Egmondville. He worked as a labourer in a brickyard.
Attached are some images you may be interested in. It's the only picture I have of Corporal Hart - and the quality is quite poor. There are also some postcards he sent home to his wife and children.
