Thank you very much for all of your research. My ancestor is the sister of Edward McCormick Sr. I found the legal record for the sale of his father's farm in Cobourg in 1868 which listed all of Edward's siblings and their spouses with their addresses. If anyone is looking for this family, Edward's parents were William McCormack and Rachael Murdoch who came to Canada about 1818 from Ireland. I have the names of the siblings and some info on them as well. William and Rachael are buried in Cobourg. The name McCormick / McCormack is spelled both ways in this family.
