Just an interesting aside.
While researching George Thom, the Scottish Minister, I found he made a payment of £13 to a Mrs Whitcomb in late 1817 or early 1818. What makes me think this is the correct Mrs W is that she was married in Gosport in 1813. Thom had finished at the Seminary in 1812.
If you have an info that may give light to this please let me know.
Best guess is that she either provided a service or was raising funds for a cause.
