All born Ontario. All Church of England
Only marriage I found of any of the above was Cecelia Matilda,d/o Alfred Naftel and Helen Pinkerton to George E Greenslade, 1910.
Alfred Naftel, s/o John Thos Naftel and Caroline Shoecome, died 21 Mar 1919.
If the above family is hers perhaps the children went to live with one of their relatives.
I found an Amy Naftel, b 1880, living in Toronto on 1911 census.
