Probably 'Bosa's ham' though the form in the Moore MS shows how early confusion with the suffix hamm arose. It is of interest to note that the neighbouring Hundred of Bosmere in Hants (DB Boseberg ), which included Hayling Island, Warblington and part of Havant, contains the same pers. name, suggesting that Bosa must have been an important early settler and that the present county boundary may not exactly correspond with the original Sussex-Wessex boundary.
