Thompson

Thompson means what it looks like: the son of Thom, the everyday short form of Thomas. What makes it English rather than Scottish is a single consonant. The medial -p- is an intrusive bilabial that crept in between the Thom- and the -son as parish clerks in County Durham and the North Riding wrote the patronymic down in a hand that ran the halves together. Across the Tweed the same name kept its leaner form, Thomson. If your family spells it with the p, that spelling was fixed in an English northern register.

It belongs to the oldest and commonest class of surname there is, sitting beside Richardson, Wilson, Jackson and Robinson, names that, as Richard Coates put it when his study of 45,602 British and Irish surnames concluded in 2016, "originally enshrined the father's name". Which means something a diaspora reader should hear plainly: there is no single founding Thompson. Every northern valley that held a Thomas raised its own line of Thompsons, independently, at the same time.

The reason the name is everywhere is arithmetic. Of the boys born in London in 1510, 24.4 per cent were named John, 13.3 per cent Thomas and 11.7 per cent William, three names covering nearly half the male population, and it held right through the Early Modern period. A parish with fifty men in it might contain seven Thomases.

That crowding is the engine. You cannot call one name across a field and expect one man to turn, so you say whose he is: Thom's son. The byname was a working tool long before it was a family name, and it was needed most exactly where the given name was commonest, which is why the patronymics of John, Thomas, William and Richard ended up with millions of bearers while rarer names never grew. The stock of given names was itself an import: after 1066 names common in France displaced Anglo-Saxon ones, and the north's first Norman archbishop was a Thomas: Thomas of Bayeux, installed at York after Ealdred's death in September 1069.

Surnames arrive in England with the Norman settlement: documented among the barons in the 11th century, generally credited to the preparation of the Domesday Book completed by 1086, with Christopher Daniell dating what may be the first surname inherited across generations to 1140.

They did not begin as things a man passed on. Early English bynames marked a trade, a father, a birthplace or a physical feature and were not necessarily inherited at all: a Thom's son could father a John's son. The habit of fixing them took hold first among the nobility and gentry, spread downwards slowly, and was resisted, because in late-medieval England compulsory surnames were associated with taxation. By 1400 most English families, and those of Lowland Scotland, had hereditary surnames; Thompson had compressed into a fixed surname by the late fourteenth century. Henry VIII, who reigned from 1509 to 1547, then ordered marital births recorded under the father's surname. By 1700 Thompson stood among the dozen most common surnames in the English north.

Plot the Thompsons of England and you have drawn an industrial map without meaning to. The name clusters on the Tyne, the Tees and across Yorkshire: the Northumberland and Durham coalfield, the Tees ironworks belt, the Sheffield and Rotherham steel district, the wool-cloth towns of the West Riding. That is no gentry distribution. It is a distribution of people who worked fire, metal and cloth where England industrialised hardest.

It is also the part of England that was most thoroughly broken and remade. William devastated Northumbria systematically in the Harrying of the North over the winter of 1069–70, and by the Domesday survey of 1086 only about 5 per cent of land in England south of the Tees remained in English hands. The Thompsons of the coalfield were not heirs of a broken Anglo-Saxon aristocracy. They were the people who stayed and worked where that aristocracy had been erased.

The Tyneside yards are where the name did its most visible work. Swan Hunter, Vickers-Armstrong and Palmers of Jarrow launched the steam-and-armoured fleets of the late-Victorian and Edwardian Royal Navy, and the slipway gangs that built them carried Thompson riveters, platers and shipwrights in numbers. A warship went together by hand, hot rivet by hot rivet.

The name is also in one of the defining images of British industrial collapse. In October 1936 two hundred unemployed men walked from the closed Palmers yard at Jarrow to Westminster to put their town's case to Parliament, and the marching ranks held a substantial Thompson contingent. If your family left the north-east in the 1930s, that shut yard is likely the reason.

Industrial skill travelled and the surname went with it, into the colonial emigration of the later nineteenth century: Cape Colony and Natal, the goldrush districts of New South Wales and Victoria, the shipbuilding towns of Ontario. By 1900 the patronymic was among the twenty most common English-language surnames in the world. In the United States just 1,712 surnames now cover half the population, and Thompson is one of that small handful, which is why the useful question for a Thompson is never which clan, but which parish.

Sir Benjamin Thompson, Count Rumford (1753–1814), is the strangest career the name has produced. Massachusetts-born and an American Loyalist, he became scientific adviser and Minister of War to the Elector of Bavaria, reforming its army and the Munich poor-relief system. Boring cannon at the Munich Arsenal in 1798 he made the foundational observation on the mechanical equivalent of heat, and back in England founded the Royal Institution at Albemarle Street in 1799.

The name's other great contribution is a book: E. P. Thompson (1924–1993) wrote The Making of the English Working Class in 1963, the foundational text of post-war British social history, and a work about the weavers, croppers and labourers of exactly those northern towns. Emma Thompson (b. 1959) holds two Academy Awards, Best Actress for Howards End in 1992 and Best Adapted Screenplay for Sense and Sensibility in 1995; in the United States Hunter S. Thompson made his name on political journalism, and J. Walter Thompson (1847–1928) founded the agency that shaped early Madison Avenue.
