I'm researching my surname McCorrister. It has been spelt Machorister, MacChorrister and for the past 100 years as McCorrister. I am a descendent of a Hudson's Bay employee at York Factory in the 1700's. I am a member of the Manitoba Geneology Society. I read everything in the society's library , the main library and the net. I am posting this in the hopes someone can tell me if my family came from Scotland or Ireland and what(if any) clan I would belong to. Please email Doug McCorrister at bluestar@escape.ca Thank you
