Other places so named are found in Shropshire and Oxfordshire, as well as Uffington Farm in Goodneston, Kent, which may also have contributed to the surname.

English : of uncertain derivation. The 18th-century parish registers of Marske, North Yorkshire, record the surname Hartburn with the variant Harburn; Harben may be a further variant of this. If so, its origin is probably topographic or habitational, from East Hartburn in Stockton-on-Tees or Hartburn in Northumberland, both named from Old English heorot ‘hart’ + burna ‘steam’. However, this conjecture is not borne out by the distribution of the surname a century later, when it occurs chiefly in Cambridgeshire and London and also with a significant presence in the Channel Islands, perhaps suggesting that it could be a variant of Harpin.
Surname or Lastname
English and Scottish
English and Scottish : metonymic occupational name for a maker of hoods or a nickname for someone who wore a distinctive hood, from Middle English hod(de), hood, hud ‘hood’. Some early examples with prepositions seem to be topographic names, referring to a place where there was a hood-shaped hill or a natural shelter or overhang, providing protection from the elements. In some cases the name may be habitational, from places called Hood, in Devon (possibly ‘hood-shaped hill’) and North Yorkshire (possibly ‘shelter’ or ‘fortification’).Irish : Anglicized form of Gaelic Ó hUid ‘descendant of Ud’, a personal name of uncertain derivation. This was the name of an Ulster family who were bards to the O’Neills of Clandeboy. It was later altered to Mac hUid. Compare Mahood.

Others, including those in Cumbria and Dorsetshire, have early forms in Hel- and probably have as their first element Old English hielde ‘slope’ or possibly helde ‘tansy’.English : some early examples such as Ralph filius Hilton (Yorkshire 1219) point to occasional derivation from a personal name, possibly a Norman name Hildun, composed of the Germanic elements hild ‘strife’, ‘battle’ + hūn ‘bear cub’. The English surname is present in Ireland (mostly taken to Ulster in the early 17th century, though recorded earlier in Dublin).

The name was reduced to Celmans and then became Le Mans as a result of the mistaken identification of the first syllable with the Old French demonstrative adjective.English (chiefly West Midlands) : status name for a particular type of feudal tenant, Anglo-Norman French mansel, one who occupied a manse (Late Latin mansa ‘dwelling’), a measure of land sufficient to support one family.English (chiefly West Midlands) : some early examples, such as Thomas filius Manselli (Northumbria 1256), point to derivation from a personal name, perhaps the Germanic derivative of Mann 2 Latinized as Manzellinus.

English : habitational name from any of numerous places named with Old English hÄlig ‘holy’ + well(a) ‘well’, ‘spring’, such as Holwell in Dorset and Oxfordshire. (Reaney suggests it could also have been a topographic name with the same etymological origin.) However, the present-day concentration of the name in Northamptonshire would suggest that Holwell in Leicestershire, which has a different etymology, from Old English hol ‘hollow’ + wella, was most likely the primary source of this form of the surname. There is also a Holwell in Hertfordshire of the same derivation, as well as places called Halwill and Halwell in Devon, Holywell in Cambridgeshire, Cornwall, Clwyd, and Northumberland, and Halliwell near Manchester, all of which could have contributed to the surname.
