Surname or Lastname
English
English : from the Germanic personal name Lanzo, originally a short form of various compound names with the first element land ‘land’, ‘territory’ (for example, Lambert), but later used as an independent name. It was introduced to England by the Normans, for whom it was a popular name among the ruling classes, perhaps partly because of association with Old French lance ‘lance’, ‘spear’ (see 2).French : metonymic name for a soldier who carried a lance, or a nickname for a skilled fighter, from Old French lance.
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.
Surname or Lastname
English
English : occupational name for a moneyer, Old English myntere, an agent derivative of mynet ‘coin’, from Late Latin moneta ‘money’, originally an epithet of the goddess Juno (meaning ‘counselor’, from monere ‘advise’), at whose temple in Rome the coins were struck. The English term was used at an early date to denote a workman who stamped the coins; later it came to denote the supervisors of the mint, who were wealthy and socially elevated members of the merchant class, and who were made responsible for the quality of the coinage by having their names placed on the coins.

English (chiefly Nottinghamshire)
English (chiefly Nottinghamshire) : nickname from the personal name Herod (Greek HÄ“rÅdÄ“s, apparently derived from hÄ“rÅs ‘hero’), borne by the king of Judea (died ad 4) who at the time of the birth of Christ ordered that all male children in Bethlehem should be slaughtered (Matthew 2: 16–18). In medieval mystery plays Herod was portrayed as a blustering tyrant, and the name was therefore given to someone one who had played the part, or who had an overbearing temper.English : variant of Harold (1 or 2).Greek : shortened form of Herodiadis, a patronymic from the classical personal name HÄ“rodiÅn. This was the name of a relative of St. Paul and an early Bishop of Patras, venerated in the Orthodox Church. HÄ“rodÄ“s ‘Herod’ is also found in Greek as a nickname for a violent man, but this is less likely to be the source of the surname.
Surname or Lastname
Scottish
Scottish : Anglicized form of the Gaelic personal name Eachann (earlier Eachdonn, already confused with Norse Haakon), composed of the elements each ‘horse’ + donn ‘brown’.English : found in Yorkshire and Scotland, where it may derive directly from the medieval personal name. According to medieval legend, Britain derived its name from being founded by Brutus, a Trojan exile, and Hector was occasionally chosen as a personal name, as it was the name of the Trojan king’s eldest son. The classical Greek name, HektÅr, is probably an agent derivative of Greek ekhein ‘to hold back’, ‘hold in check’, hence ‘protector of the city’.German, French, and Dutch : from the personal name (see 2 above). In medieval Germany, this was a fairly popular personal name among the nobility, derived from classical literature. It is a comparatively rare surname in France.

Two originally distinct names have fallen together in this form: one was a short form of compound names with the first element gail ‘cheerful’, ‘joyous’. Compare Gaillard, the other was a byname from the element walh ‘stranger’, ‘foreigner’.English : metonymic occupational name for a jailer, topographic name for someone who lived near the local jail, or nickname for a jailbird, from Old Northern French gaiole ‘jail’ (Late Latin caveola, a diminutive of classical Latin cavea ‘cage’).Portuguese : from galé ‘galleon’, ‘war ship’, presumably a metonymic occupational name for a shipwright or a mariner.Slovenian : from a pet form of the personal name Gal (Latin Gallus), formed with the suffix -e, usually denoting a young person.
