British Names

This essay is the same on the pages of all 59 countries that use the tradition, and what differs between them, their registers and their rankings, is on those pages.

The United Kingdom of Great Britain and Northern Ireland comprises four countries: England, Northern Ireland, Scotland, and Wales. English is spoken throughout, with dialect variation alongside Standard British English; the Celtic languages Welsh, Scottish Gaelic, and Irish remain historically and culturally important in parts of the UK. Christianity is the dominant religion (72% self-identifying as Christian, most of them Protestant). Names are written in the Latin script.

Structure & order

The standard order is given name(s) first, hereditary surname last:

[GIVEN] ([MIDDLE]) [SURNAME]

Hereditary surnames were first adopted by the nobility in southern England after the Norman Conquest of 1066, then spread over several centuries to the upper classes and eventually throughout society across the British Isles, in some remote parts as late as the early nineteenth century. Before the Conquest it was very rare for a person to be recorded with more than one name (e.g. Alric, Thorald, Wulfstan); intermediate non-hereditary bynames described an aspect of their bearer and died with the individual rather than passing to offspring. Recent immigration has re-introduced non-hereditary surnames on a small scale.

Given names

Forenames are chosen by the parents. That choice became freer during the twentieth century as systems encouraging naming after relatives were abandoned; the turnover of most-popular names increased and, most markedly, the number of separate names bestowed multiplied (so a child is much less likely to receive a current top-ten name). Hypocoristic (pet) forms have become popular as official forms in their own right (e.g. Jack, Ellie).

Given names come from a variety of sources:

Biblical names
Classical names
a small number of Germanic names
Continental names (many adopted after the Norman Conquest)
surnames used as forenames
place-names (often via surnames)
Celtic names (particularly in areas of recent Celtic heritage)

Some names share an original source but were modified through different languages, e.g. John (English) / Sean (Irish) / Iain (Scottish Gaelic) / Evan (Welsh).

Top names (2010 / combined figures):

Male (England & Wales 2010): Oliver, Jack, Harry, Alfie, Charlie, Thomas, William, Joshua, George, James
Female (England & Wales 2010): Olivia, Sophie, Emily, Lily, Amelia, Jessica, Ruby, Chloe, Grace, Evie
Surnames (UK combined): Smith, Jones, Williams, Brown, Taylor, Davies, Wilson, Evans, Thomas, Roberts

Family names & patronymics

Women usually assume their husband's surname on marriage. English surnames (and, using the same typology, Scots surnames) fall into four broad origin categories:

Type	Description	Examples
Relationship (patronymic)	Identifies via relationship, usually to the father. English patronymics often add suffix -son (Johnson) or its equivalent -s (Roberts); some simply use a name with no suffix	Johnson, Roberts
Locative	From ownership of estates (upper classes) or place of origin/abode (lower classes). Subdivides into topographical (a landscape feature: Hill, Ford, Marsh) and toponymic (a pre-existing place-name: Burford, Blakeway, Copplestone)	Hill, Burford
Occupational	From a trade; some transparent today (Baker, Smith — the commonest surname of all), others fossilized (Wright, Chandler). Status names (Knight, Squire) are a subdivision. Some began as metonymic nicknames (Cheese = cheesemaker/seller; Wastell = maker of fine cakes)	Cooper, Smith
Nickname	From a physical or behavioural characteristic; varied but include common surnames	White

Celtic prefixes show relationship rather than using a suffix:

Scottish Gaelic: prefix Mac 'son of' (most typical).
Irish: can begin Mac/Mc, but more often the prefix O' 'grandson/descendant of'. The prefixes Mac and Ó were dropped during the submergence of Catholic/Gaelic Ireland (from the early 17th c.) and re-emerged in anglicized form in the late 19th c.; since the 1960s there has been a resurgence of Irish-language (Gaelic) forms.
Manx: ~200 distinctively Manx surnames survive in Britain, many beginning C- (Clague, Cretney) or Q- (Quirk, Quinney), residues of Gaelic Mac-.
Welsh: prefix ap- 'son of', anglicized in many surnames to P- (e.g. Pugh, Price).

How to address someone

Married women usually take their husband's surname. The standard English courtesy titles Mr, Mrs, Miss, and Ms precede the surname (general knowledge). The sources do not otherwise detail UK-specific honorifics.

Pitfalls for software

One surname, four origin types. A British surname's form does not reliably reveal its category: Smith may be occupational (English) or an anglicization of Irish Mac a'ghobhainn 'son of the smith'. Bird anglicizes several unrelated Irish names containing éan, by folk etymology.
Patronymic suffix vs. prefix. English uses suffixes (-son, -s); Celtic languages use prefixes (Mac, O', ap/ab). The same root can surface either way.
The Welsh -s problem. Jones, Williams, etc. are patronymics in disguise, the -s stands in for ab/ap, so a "surname" is really "(son) of [given name]". Welsh surnames are thus heavily drawn from a small pool of given names, producing high frequency collisions.
Hidden patronymic prefixes. Pugh and Price hide Welsh ap- (→ P-); Manx Quirk/Clague hide Gaelic Mac-. Software keying on the literal Mac/Mc/O'/ap strings will miss these anglicized forms.
Irish prefix volatility. O' and Mac were dropped and later re-added over centuries, so the same lineage appears as Sullivan and O'Sullivan at different periods.
Cross-border surname exchange. Surnames have moved between Britain and Ireland for ~1,000 years (Norman Butler, FitzGerald; Border-reiver Nixon, Armstrong, Paisley into Ulster; Irish names back into Lancashire, Glasgow, south Wales), so a surname's form is a weak guide to a bearer's home nation.
Statistics mask variation. UK-wide name frequencies hide strong regional and social-class variation; the home nations even collect data through separate agencies (ONS for England & Wales; GRO Scotland; NISRA for Northern Ireland).

Welsh patronymics and the -s collapse

The Welsh system used mab 'son' in the form X mab Y. Lenition turned mab → fab → ab (the Welsh f sound, probably bilabial, was easily lost). Generally ab occurred before names beginning with a vowel and ap before names beginning with a consonant (e.g. Madog ab Owain, Madog ap Rhydderch), though not all recorded names follow this. Hereditary surnames were still rare in Wales even by 1500; the shift to settled surnames only began filtering through society in the mid-sixteenth century, causing the loss of ab/ap in many names.

Two outcomes explain modern Welsh surnames:

The -s collapse: the English genitive -s replaced Welsh ab/ap in many cases, producing typically Welsh surnames like Jones and Williams (common in Wales since at least the 16th c.).
Metanalysis: ab/ap fused with the following name, e.g. Thomas ap Howell → Thomas Powell. This was most common near the English border; in other areas the ap patronymic survived as late as the eighteenth century. A revival of X ap Y personal names occurred in the second half of the twentieth century through renewed national awareness.

The corresponding Welsh "daughter of" form is verch / ferch (from merch 'daughter'), parallel to ap/ab. (general knowledge, the sources cover only ab/ap "son of")
