It generated a great many variant diminutive and patronymic forms in the Middle Ages of which "Thew" was one of them.

Later examples taken from the surviving church recordings of the early city of London include: Elizabeth Thow, who marrried William Bookhall at the church of St Gregory's by St Pauls, on November 1st 1578, and Edward Thew who married Mary Carnon on July 25th 1639, at St. Giles Cripplegate. The first recorded spelling of the family name is shown to be that of Gilbert Thewe.
