barkingbunty on Family Tree Circles

Hi I am trying to trace my great uncle Arthur Foster Collin born 1890 Lincolnshire Englnd. I know he travelled to Calgary Canada around 1911 when he joined the Canadian Overseas Expeditionary Force. I know he returned to England and married Alice May Green in 1918 in Suffolk and was working as a cabinet worker. I believed he emigrated to Canada around 1928 and if I am correct he died in Calagary in 1972 and was burried in Queens Park Cemetery. I would appreciate very much if some one could tell me how I can back this up and trace any ancestors of his.
thankyou
