I am a descendent of Robert Laxton, son of Clement, (through Claude and Carl). Do you have any information about Clement in England when he was married to Lucy Lancaster? Did he have children there? How did he came to the U.S.?
I visited the village of Laxton near Nottingham in the 1990s. No Laxtons buried in the cemetery there, however, the name of Richard de Lexington (1170) came up in the history of Laxton, or Lexington. I don't know if there is a connection or not.
