BILL THOMAS

Altered short form of William, not used before the 19th century. The reason for the change in the initial consonant is not clear, but it conforms to the pattern regularly found when English words beginning with w- are borrowed into Gaelic. The nickname ‘King Billy’ for William of Orange is an early example from Ireland, which may have influenced English usage. It is bestowed occasionally as a name in its own right.

English, French, German, Dutch, Danish, and South Indian: from the medieval personal name, of Biblical origin, from Aramaic t’ōm’a, a byname meaning ‘twin’. It was borne by one of the disciples of Christ, best known for his scepticism about Christ's resurrection (John 20:24–29). The th- spelling is organic, the initial letter of the name in the Greek New Testament being a theta. The English pronunciation as t rather than th- is the result of French influence from an early date. In Britain the surname is widely distributed throughout the country, but especially common in Wales and Cornwall. The Ukrainian form is Choma. It is found as a personal name among Christians in India, and in the U.S. is used as a family name among families from southern India.
