I am the great grand daughter of Christina Wilson and Robert Ironside. Your message says their children were born in the 1920s, but that would make Christina in her 50's at that time. My grandmother (the girl) was born in 1902. My mother was born in 1925. Christina must have died before the end of WW1 as Robert Ironside emigrated to Canada with my grandmother and his new wife just after the war. They settled in Winnipeg, Manitoba, Canada. I have no knowledge of a boy. Very curious to know your connection with the family and would love to learn more. I have a copy of Robert Ironside's newspaper obituary.
