BEST
As described in historical dictionaries
Patronymica Britannica (1860)
BEST. BESTE. This name has probably no connection with the adjective. In the H. R. it occurs as Le Beste, ' the beast,' a sobricjuet ; but there is one well-authenticated instance, in which it is a corruption of the Norman Basset. Inf. Stacey Grimaldi, Esq., F.S.A.
