Irish
Irish : in part at least, probably a further Anglicization of the Irish surname Mountcashell, itself an Anglicized form of Gaelic Ó Maolchaisil (see Cashel 2), which was associated with Ballymulcashell in County Clare. Woulfe says that a registrar in Munster changed the name to Mountcashel c. 1840.English : in England, this name is common in Lincolnshire. While this may well be the result of migration from Ireland, the possibility of a habitational name from an unidentified place should not be ruled out.

English (mainly southeastern)
English (mainly southeastern) : variant of Hook (in the occupational or topographic and habitational senses), with the addition of the agent suffix -er.Congregational clergyman Thomas Hooker (1586?–1647) sailed from England with John Cotton and Samuel Stone and arrived in Boston in 1633. He led the 1635 migration of most of his congregation to Hartford in the Connecticut Valley. Thomas is the earliest known entrant, but the name Hooker is common and was also introduced independently by others during the 17th and 18th centuries.
Surname or Lastname
English (Yorkshire)
English (Yorkshire) : habitational name from a place in Yorkshire, recorded in Domesday Book as Schipwic, from Old English scēap, scīp ‘sheep’ + wīc ‘outlying settlement’. Under later Scandinavian influence the initial ‘s’ became ‘sk’ and the second element was changed to -with (Old Norse viðr ‘wood’).The main Skipwith family held the manor of Skipwith in England in the early Middle Ages, and direct descendants can be traced to the present day. In the 13th century they moved from Yorkshire to Lincolnshire, where their principal seat was at southern Ormsby. In the early 17th century there was further migration, to Leicestershire, Warwickshire, and across the Atlantic to VA. Other bearers of the name seem to have been tenants of Lincolnshire manors held by the Skipworth family, and to have taken the surname of their overlords.
Surname or Lastname
