Thanks very much for this Len.
I was trying to track this connection but could not find a Margaret Quine as one of Thomas & Isabella Quine children & sibling of Anne Quine listed in the 1841 census. But since I have her born in 1820 (Bap 26 Dec 1820) she would be 21 in 1841 and either married to James Gill or at least living elsewhere. According to the 1851 census for James & Margaret Gill there is a son Thomas, age 11, so they were probably married before the 1841 census.
