Do you have details of Margaret Curphey's siblings and parents ?
Looking back through the censuses at the family you mentioned, have I got the right one---father John Curphey, mother Christian ?
The IGI has Christian's maiden name as Davidson, and her marriage to John on 21st Feb 1843.
Their children are listed as:

This bulletin board thread has become difficult to keep track of, with its parallel messages. Did I see in one of your earlier messages the name Gick ? One of the brothers of this Margaret has got a middle name of Gick. Is this significant ?
