There is likely to be a connection with the Tompkins family I have in Marsh Gibbon which is just a few miles from Finmere. Can't be deifinate about this as all I have so far are three children born to William Tompkins, b 1801, M Gibbon and his wife Sarah Clements. These are, Edwin, b 1847, Ann b1849 and Ellen b1856.
