My one-name study began following on from researching my family history.The Cosworth surname came in to being during the 18th century when my 5 x great-grandfather married Catherine Cosworth in 1778. When asking my father why my middle name was Cosworth, a name which both my brother and father also had,the explanation was that it was a London name (my father was born in the East end of London) which had been passed down the male line over the years. However, my research indicated otherwise.Not only did it not pass down from father to son(s), on occasion it could be found intermittently on the female side as well.
The Cosworth name has its roots in Cornwall and the objective of this study is to find out the origin and development of the Cosworth surname.
Variations of the Cosworth name include: Cosowarth, Cosworthy, Cosworthie, Cosword, Cosward, Kosworth, Causeworth, and Cusworth.
The origin of this name extends back to the time when surnames were not used, and when they came into being, they were frequently taken from the place in which a person lived or worked. These are know as Location names, being either topographical or habitational. Another method used was Patronymics, meaning the name was derived from a person i.e. Johnson (John's son).
The place called Cosworth is to be found in Colan, Cornwall. It is listed in folio 12v of the Great Domesday Book as being the place name of Cudiford/Gudiford (King's Land which was formally of St Petroc's Church in 1086). A previous name of this area was Cudjore, which meant wood-play. Sir Simon Cosworth would sometimes style himself Sir Samuel Cudjore for Cudchoario, the name by which the woods were known. Cosowarth was a later name and this meant "the further off woods", when the woods on the south-west part were destroyed.
At the time of the Norman Conquest, the French family name of Escudifer, meaning "shield bearer", was trans-nominated to that of Cosworth.
