William Hatch

(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 Hampshire and Berkshire): topographic name from Middle English hacche ‘gate’, Old English hæcc (see Hatcher). In some cases the surname is habitational, from one of the many places named with this word. This name has been in Ireland since the 17th century, associated with County Meath and the nearby part of Louth.
