Thanks Jim, I've updated the base note.

There are a core of surnames that crop up -- Marfell, Meek, Teague, Trigg, Vaughan( to name a few) plus the Davis / Davies, Griffiths, James, Jenkins, Jones,Morgan, Thomas, Watkins, Williams. Now I think I have covered 80%

For the final 20% Baldwin, Brain, Cowmeadow, Grindle, Gwillam, Hale, Powell ,Sterry etc
