Haysom Family History

Perhaps from Haysend in Tamerton Foliot (Devon), recorded in the surname of John de Hayeshende 1332 in Subsidy Rolls (Devon). The place-name may derive from Old English (ge)hæg ‘fence enclosure’ (genitive hæges) + ende ‘end of an estate’. The alteration of -send to -som and -son would be unexceptional.

Alternatively, it might, like Heesom, be an altered form of Eastham, but the evidence is inconclusive. Possibly a variant of Hayson (1), but medieval names in -son are rare in SW England where this surname is mainly found.
