John and Ellen Young.
Somewhere in Nova Scotia.
Your daughter Emma Georgina, born in July of 1860, is my great-grandmother. She immigrated to the US in 1881 and on 23 July of the same year, she married my great-grandfather James Brinton (Brenton) Johnstone in Boston, Massachusetts. They lived in Winthrop, where my grandaunt Maud Sherlock Johnstone (1886-1917) and my grandmother Blanche Evelyn Johnstone (1888-1994) were born. There was another child, according to the 1900 US Federal Census, but I haven't found any record of that birth.
James B. Johnstone was born in Shelburne, Nova Scotia. I checked the 1871 census - you were not there. You were also not in Sherbrooke where my father said you may have come from; or Guysborough a town that I have in mind, but probably only because I found a census with George Young who had a daughter Emma way back before I knew that you and Ellen were Emma's parents.
So where are you?
