Find Ancestors

Ancestors in Ontario, Canada: I`m tring to find details of my ancestors who went to Canada in the 2nd half of 1901. Harry Francis Hector HUXTABLE b1881 worked for the Soo Ferry Dock before working as an auditor for the Algoma Railway. He lost an arm in France during WW1 and had a hook for a hand. I have Harry`s Attestation papers from the internet. His sister Edith/Edyth Alisia Alice HUXTABLE b1874 was a dressmaker before running a boarding house on Bay St. Both are buried in Greenwood Cemetery (Harry 1960 / Edith 1965.) Neither of them married. Allegedly sister Mabel Agnes Blanche HUXTABLE b1877 also travelled with them, but returned home soon after. She told everyone back home it was too cold for her, but rumour has it that she witnessed a murder and fled! Their young nephew Claude R. (Roland?) SMITH was with them, but as I have no date of birth for him he may have been a newborn or a 10 year old child at the time! Claude SMITH married Nellie Ellen FAY. Claude & Nellie`s son Roland SMITH was killed in a car crash when he was 24 years old, on 26th June 1951. I`d like to find out if Claude and Nellie had other children, otherwise my family line will sadly cease in Canada as Roland wasn`t married when he died. I`d also like to find out about Claude and Nellie`s marriage certificate (probably c1926 judging by Roland`s age) as it would be great to get his age / names of witnesses etc. I have a little more info if needed and would be grateful of any fresh data. Karen.
