Some sources claim the husband of Margaret Malet and father of Robert Brent, alias John Buston, was named John, but this seems to be based on confusion of preceding and succeeding generations.

John Collinson's "History and Antiquities of the County of Somerset" (London, 1791) records in volume III: "The eldest son of this John Brent was called Robert, and married Margaret, daughter of Hugh Malet, of Currypool, by whom he had another John, who added to his estate the manors of Goodwin's Bower and West Bagborough, which he purchased of Thomas Godwyn, as also (from his wife Maud, the daughter and co-heir of Sir Walter Pauncefoot, the Manor of Compton-Pouncefoot, and Pouncefoot Hill, all of which descended to William Brent, their eldest son, under age." (John Collinson, as quoted by C.H. Brent, p. 29)

"De Bow's Review" also supports that this man's name was Robert. "The aforsaid Robert, son of Robert by Margaret, in 1487, came to Stoke..."
