This is probably really late giving these posting dates, and I'm sure you're so far ahead of me given I only started a week or so ago, but here goes:
My mom went into a genealogy phase and ended up getting some oral history out of her grandmother, Lulu Grace, when the latter was in her 80s. Supposedly, she barely remembers living with her family at all, and was sent off as a toddler to live in Kingston with her older sister Vena (Alvena). Supposedly, years and years later, Leonard came along from Sudbury (already married I believe) and found them, saying they were long lost siblings...he'd grown up supposedly with French relatives. Supposedly, Lulusaid her parents had divorced or separated.
Also, supposedly both my mom's mother and grandmother claimed there was a native component to their ancestry (supposed to be Lulu's mom, or in this case Mary Louisa Currier). I was always told that Lulu's dad was a coureur-de-bois and was French, from near Sudbury.
But, then again, my mom only remembered Lulu's last name was McGillis and not Courrier when I started my hunt a few weeks ago.
Anyway, safe to say, the 1901 and 1911 census add lots of confusion, and a few Great Aunts and Great Uncles to my mom's family tree.
Also, google around until you get links to a williamdavidson.com page that has the Currier family linked back to Leontheuil de Bayeux in Normandie.
