Yes, Dr. Marriott was married to my great-aunt Ellen Everett Marriott. I know that they lived in Swaffham and had numerous children, only one of whom left children of her own. I don't know a lot about Dr. Marriott's family. In letters written by my great-aunts to my grandfather he is referred to as Uncle Buchanan, probably because the Everett's had a lot of their own Roberts.
