The 1861 census for Yonge Twp, Leeds Co, ON (where Brockville is located) shows the following:Peter, born Upper Canada, age 31, Jane, born Ireland, age 25 and the following children born Upper Canada:Rile, 9, Isaac, 7, Joseph, 2.Living with this family was Betty, born USA, age 60 (whom I believe is Peter's mother also known as Elizabeth).I think that Peter was the son of Joseph (b. Elizabethtown, ON) and Elizabeth.I think that Peter's siblings could include Philip b. ca. 1825, Isaac, b. ca. 1832, Delia b. ca. 1836 and Jane b. ca. 1838.
