Hi Mick ,
Thanks for the link to John Davy's biography . It does state that their family had lived in Ludgvan for " more than 200 years " and the parish register recorded their births and deaths back to 1588 . And although Humphrey was of the opinion that the origin of the family came from Norfolk , that in itself hardly links those families of Norfolk and Cornwall ; especially as " there was a family tradition that they were originally of Norman extraction and had come over with William "
Best wishes ,
