Hi Justin, In the last on line census, there were 1,712 Foords in England Scotland and Wales, but in Wales there were only four, so by now there could possibly quite a few.
Just checked 2013 Electoral rolls in Wales 22, in Britain 1174
Also have you tried Freereg I found five Foords baptisms 1596 to 1720, three in London, two in Sussex, and that was only on a selection of some South Wales counties and London and some southern counties, eight counties in all, you can't search for all counties, also I didn't look at Marriages and Burials.
best wishes Rowley
