It sounds as if we might possibly be looking at the same family. I have a William Morgan living at Oak House, but born in about 1680/90 in the Vale of Evesham. I have tried to tie him in with the Tredegar Morgans, as family legend has it, but with no success. I have also visited Oak House for myself. Three generations later one of William's descendants marries into the Chamberlain family. Does this feature in your tree?
