Robert drowned by misadventure and the others barely escaped to land. Inquest before the same coroner [Simon Rufus, or, the Red] by Wyboston, Eaton Socon, Chawston and Colesden…Robert's sister Rose first found him, raised the hue, which was followed, and found pledges, William son of Ralph le Carun and Henry Mile of Wyboston.
