James Ainslie who was born April 1798 in Greenlawalls, Norham Northumberland emigrated with his parents George and Isabel Ainslie to Quebec in 1822 I believe. Jock Ainslie who lives in Niagara Falls Ontario has done a huge book on the Ainslie family tree that is on file at the National Library of Canada.
James ended up in Tilbury, Kent County Ontario and had 10 sons and 1 daughter there with his wife Elizabeth Laing. I believe James brother George and his sister Isabella who married a William Hope also ended up there. I can check Jock's book (which is at work not at home) for further details if you like Glenda. ( in case you are wondering James older brother John was my 3 gt grandfather and he stayed in Quebec)
