The name Jillem was carried to England in the enormous movement of people that followed the Norman Conquest of 1066. It comes from the Old French given name Guillaume. The name Guillaume was modified into two forms after arriving in England: Gillham and William.

Early Origins of the Jillem family

The surname Jillem was first found in Suffolk where Giliana was listed in the Feet of Fines in 1198. 1 Many of the family stayed in Normandy as in the same year, Udon Galien was listed there. 2 Due the prevalence to the often personal name, the name was scattered in early censuses as show by the Rotuli Hundredorum of 1279 which listed Gilianus de Levekenore Buckinghamshire and Adam filius Jellion in Cheshire. 1

Years later the Yorkshire Poll Tax Rolls of 1379 listed the name as both a personal name and a surname: Petnis Gillam; Willelmus Giliam; Giliaum Spyser, 1379; and Ricardus Gillumman, i.e. the servant of Gillura. 3

Susan Gilham made her home in Jamaica in 1661; Susan Gilham settled in Barbados in 1661.
