I have these 2 in my family. They are the grandsons of Samuel Waymouth, Tobacconist of Exeter. I don't know if they're descended from Sheriff George, as I haven't been able to get back beyond Samuel's (probable) marriage to Mary Smith in 1718. The name George is extraordinarily rare in this family - this is the only one I know of. Their family was strongly non-conformist. The Rev Charles is connected - a great grandson of Samuel, through 2 generations of Johns.
