The meaning of Coslett
German and Welsh: from early modern German korselett ‘corslet, piece of body armour’. The name is said to have arrived in Wales from Westphalia in the person of Corslet Tinkhaus, an expert in the production of malleable iron, who came in 1567 at the behest of an Elizabethan monopoly patent-holder for iron wire, William Humfrey, active in Usk and Tintern (Monmouths) and Machen (Glamorgan). If that is correct, Tinkhaus’ personal name (or rather nickname) was inherited by his descendants rather than his surname. The English loss of /r/ before /s/ has many parallels, e.g. in cuss for curse.
