I think we are barking up the wrong tree when we are looking in Scotland and Ireland. I found a Gupton farm in Pembroke and contacted the owners. They had no idea where the name came from, but apparently there had been some Gupton's there at some time or another. The "ton" ending of the name is indicative of a place a "ton" or "town" and many of our English ancestors got their names from where they lived. Maybe I am wrong, but I don't feel we need to limit ourselves to Ireland and Scotland.
