William Hartley

(male) Probably the most successful of all the Old French names of Germanic origin that were introduced to England by the Normans. It is derived from Germanic wil ‘will, desire’ + helm ‘helmet, protection’. The fact that it was borne by the Conqueror himself does not seem to have inhibited its favour with the ‘conquered’ population: in the first century after the Conquest it was the commonest male name of all, and not only among the Normans. In the later Middle Ages it was overtaken by John, but continued to run second to that name until the 20th century, when the picture became more fragmented.

English (mainly northern): habitational name from any of various places so called. Several, in particular those in Hampshire, Kent, and Devon, are named from Old English heorot ‘hart’, ‘stag’ + lēah ‘wood’, ‘clearing’. One in Northumberland has as the second element Old English hlāw ‘hill’, and one in Cumbria contains Old English clā ‘claw’, in the sense of a tongue of land between two streams, + probably heard ‘hard’. The surname is widely distributed, but most common in Yorkshire, where it arose from a place near Haworth, West Yorkshire, also named with Old English heorot + lēah. As a Scottish name, it comes from the Cumbrian Hartley (see forebears note).
