I agree with my cousin Kat - I do not see a child Margaret born to David & Olivia in 1899 - check out the 1901 online census for Canso - you will see David, olivia, and their children - daughter "Clear" (Claire) born Feb 8, 1898. Dau. "Lolla" (Lola) born Apr 4, 1900. with no child between them in age. There IS another David Greencorn living in Canso in that same time period - perhaps he is your relative? This "other" David Greencorn has confused me sometimes, too.
