Dear Sandymc,
Thank you soooooo much! I am most delighted to have this. So, Ann's (with no "e") family name was Allan! Yes, I have 8 children for Christopher & his wife Rebecca in my record: William, Mary, Sarah, Ann, Christopher, Rebecca, David, Hannah. I believe this family, or part of it, arrived at the Port of New York aboard the Chester in 1843. From there they came to Ontario, although I cannot account for all the children. I am descended from David, or so I believe.
Is the source you used accessible to me? I am guessing it is possible that "Russel" with one "l" somehow became "Russell" with 2 "l's"?
With thanks, Jaunty
