I don't know why she's not on the 1881 census but you will see Edith on the 1901 Canadian Census for Lockhartville, Nova Scotia.
The only one that went to the United States was Charles (or William) Gould.
I'm most interested in the three girls and what happened to them and Charles Gould.
Does any of this sound familar? We have a pretty good history of our side of the Allens before the 3 girls but nothing but a mystery when it come to them. Besides my Grandmother, Marguerite, we don't know what become of the other 2 girls or Charles Gould.
