Surname or Lastname
English, Welsh, French, South Indian, etc.
English, Welsh, French, South Indian, etc. : from the personal name George, Greek GeÅrgios, from an adjectival form, geÅrgios ‘rustic’, of geÅrgos ‘farmer’. This became established as a personal name in classical times through its association with the fashion for pastoral poetry. Its popularity in western Europe increased at the time of the Crusades, which brought greater contact with the Orthodox Church, in which several saints and martyrs of this name are venerated, in particular a saint believed to have been martyred at Nicomedia in ad 303, who, however, is at best a shadowy figure historically. Nevertheless, by the end of the Middle Ages St. George had become associated with an unhistorical legend of dragon-slaying exploits, which caught the popular imagination throughout Europe, and he came to be considered the patron saint of England among other places.

English : from the expression ‘God speed (you)’; a wish for success for one setting out on an enterprise, presumably applied as a nickname for someone who habitually used this expression.
Surname or Lastname
English (Norfolk)
English (Norfolk) : from Middle English gode ‘good’ + body ‘person’, ‘creature’, apparently a nickname for a good person. Reaney, however, notes that the expression was used as a polite term of address, and the surname may therefore have arisen as a nickname for someone who habitually used this expression.
Surname or Lastname
English
English : status name from Middle English knyghte ‘knight’, Old English cniht ‘boy’, ‘youth’, ‘serving lad’. This word was used as a personal name before the Norman Conquest, and the surname may in part reflect a survival of this. It is also possible that in a few cases it represents a survival of the Old English sense into Middle English, as an occupational name for a domestic servant. In most cases, however, it clearly comes from the more exalted sense that the word achieved in the Middle Ages. In the feudal system introduced by the Normans the word was applied at first to a tenant bound to serve his lord as a mounted soldier. Hence it came to denote a man of some substance, since maintaining horses and armor was an expensive business. As feudal obligations became increasingly converted to monetary payments, the term lost its precise significance and came to denote an honorable estate conferred by the king on men of noble birth who had served him well. Knights in this last sense normally belonged to ancient noble families with distinguished family names of their own, so that the surname is more likely to have been applied to a servant in a knightly house or to someone who had played the part of a knight in a pageant or won the title in some contest of skill.Irish : part translation of Gaelic Mac an Ridire ‘son of the rider or knight’. See also McKnight.

English : nickname for a noisy person, from Middle English lude ‘loud’ (Old English hlūd), perhaps in part preserving the Old English byname Hlūda that Ekwall postulates to explain the place names Loudham (Suffolk) and Lowdham (Nottinghamshire).English : topographic name for someone who lived by a roaring stream, Old English hlūde or hl̄de literally ‘the loud one’, or a habitational name from any of the places named from hl̄de, for example Lyde in Herefordshire and Somerset.English : variant of Louth.

English : habitational name from Middle English, Old French ju(ie)rie ‘Jewish quarter’, often denoting a non-Jew living in the Jewish quarter of a town, rather than a Jew. Most medieval English cities had their Jewish quarters, at least until King Edward I’s attempted expulsion of the Jews from England in 1290. This did not succeed in expelling the Jews, but it did give a license to persecution and so broke up many of the old Jewish quarters.

English : from the popular medieval personal name Hudde, which is of complex origin. It is usually explained as a pet form of Hugh, but there was a pre-existing Old English personal name, Hūda, underlying place names such as Huddington, Worcestershire. This personal name may well still have been in use at the time of the Norman Conquest. If so, it was absorbed by the Norman Hugh and its many diminutives. Reaney adduces evidence that Hudde was also regarded as a pet form of Richard.German : from a short form of a Germanic compound personal name formed with hut ‘guard’ as the first element.Variant spelling of German Hütt (see Huett).Jewish (Ashkenazic) : metonymic occupational name from Yiddish hut, German Hut ‘hat’ (see Huth).

Scottish : habitational name from a place the location of which is disputed. Black gives two Scottish options, the first with no explanation, the second being Halley in Deerness, Orkney. Modern Scottish bearers may well get it from the Irish names (see 3 and 4 below).English : in part possibly a habitational name from Hawley in Hampshire, named from Old English heall ‘hall’, ‘large house’ + lÄ“ah ‘woodland clearing’.Irish (Counties Waterford and Tipperary) : shortened Anglicized form of Gaelic Ó hAilche ‘descendant of Ailche’, possibly from the byname Ailchú meaning ‘gentle hound’.

English : from a medieval male personal name (from Latin Hilarius, a derivative of hilaris ‘cheerful’, ‘glad’, from Greek hilaros ‘propitious’, ‘joyful’). The Latin name was chosen by many early Christians to express their joy and hope of salvation, and was borne by several saints, including a 4th-century bishop of Poitiers noted for his vigorous resistance to the Arian heresy, and a 5th-century bishop of Arles. Largely due to veneration of the first of these, the name became popular in France in the forms Hilari and Hilaire, and was brought to England by the Norman conquerors.English : from the much rarer female personal name Eulalie (from Latin Eulalia, from Greek eulalos ‘eloquent’, literally well-speaking, chosen by early Christians as a reference to the gift of tongues), likewise introduced into England by the Normans. A St. Eulalia was crucified at Barcelona in the reign of the Emperor Diocletian and became the patron of that city. In England the name underwent dissimilation of the sequence -l-l- to -l-r- and the unfamiliar initial vowel was also mutilated, so that eventually the name was considered as no more than a feminine form of Hilary (of which the initial aspirate was in any case variable).
