The second suggestion is that the name derives from the medieval English 'dipper' meaning a 'diving bird' or 'kingfisher' and was originally given as a nickname to one skilled in diving or fishing. Variations in the idiom of the spelling include Dipere, Dipper, Diaper, etc.. One Johnas Diaper married Elizabeth Harrwth on July 25th 1568 at St. Andrew, Enfield, London and William, son of John Diaper, was christened at St. Botolph, Bishopsgate, London on July 2nd 1592. Alternate spellings include le Dipere (1227), Dipper (1520) and Diaper (1687) Buxhall, Suffolk. The first recorded spelling of the family name is shown to be that of William de Ipra, which was dated 1140 Seals of Lincolnshire, during the reign of King Stephen, 'Count of Blois', 1135 - 1154.
