Just to clarify a few points, my understanding is that the husband's grandmother was not married at the time his father was born, which is why the husband's father was given the name of his maternal grandfather, Webb. The DNA shows that the husband matches a current Stewart from 370 years ago (i.e. a pretty distant relative); a closer relative may eventually join the DNA project. I'd advise looking at Census and land records for the husband's grandmother and great-grand-father to see if a Stewart turns up anywhere. My great-aunt was living with her future husband in a boardinghouse in the 1930 US Census.
