Langhorne Family History

English:: apparently from Middle English lang ‘long’ + horn ‘horn’ later modified to Standard English Longhorn. Perhaps the nickname alluded to a long fingernail or toenail one of the senses of horn in Middle English.

(northern): habitational name from Longthorn Hill in Soulby (Westmorland) possibly named with Old English lang ‘long’ + horn ‘projecting piece of land’ although the earliest record of this place (Longhorne-crooke 1693) is very late; it may have been so called after the English surname (see 1 above).
