Samuel John (S.J.) Dempsey (Dempsay)who came to Canada circa 1871, was my grandfather. James Shannon Dempsey was my "uncle Jim". S.J. was married twice. His second wife - Ida Virgin" was my grandmother. S.J. settled in Calabogie, near Renfrew Ontario, and around 1910 moved to Cochrane Ontario. One of my cousins has written a book on the family of S.J.. I have met some of the Virgin family. I know a fair bit about the Dempseys. My mother was Vera Dempsey. All of S.J.'s 17 children are now dead. There remains an American branch of the Dempseys.I would be interested in hearing from Sharon Kirkman
