1690 (approx) - unknown
All we know of this lady is contained in an old family tree, probably compiled in the early 19th century, which shows the following:
Agnes Gammell (sister of William Gammell, ship master) married Wm Thomson in Netherton. They had 2 children, Andrew Thomson, farmer in Netherton, and Alexander Thomson shipmaster in Port Glasgow. Andrew had 4 children, Wm. Thomson, Shipmaster in Greenock and 3 daughters. Alexander had one child, Margaret Thomson, who married her cousin Wm. Thomson. They had one child William Thomson in Newfoundland.
We have no dates for any of these people, and all we know is that a certain Andrew Thomson was a founding member of the Greenock Bank in 1785 in conjunction with James Gammell, and that the latter in his will dated 1825, left a legacy of £200 to William Thomson. It is also fairly certain that the Andrew Thomson of the Greenock Bank, was either in or had close connection with Newfoundland, and that of course Agnes Gammell/Thomson was James Gammell, the banker's aunt.
