I know the family you are referring to: they were in Brampton Bryan, on the 1881 Census. I expect there may prove to be a connection, as George was a gamekeeper too. Probably brothers, but my own connection is with Jemima and her descendants. Will let you know what I can find on her descendants. It may interest you to know that both your Samuel and his wife left wills, as did a number of their descendants, though I don't have these.
