I'm looking for a BLANCHFLOWER family whose children were born in Norwich. I believe the entire family emigrated to Canada in the 1830s. The children that I know about are:

Mary, b. 1820/1822
Samuel, b. 5 Jan 1822
Jane, b. 1823/1829
John
Sophia (possibly born in North America)

Does anybody recognize this family? I have no names at all for the parents, and no clue about John's and Sophia's dob.

Thanks!
