This is one of the patronymic forms of the name 'Edgar', which is a personal name of Anglo-Saxon origin, derived from the Old English pre 7th Century 'Eadgar'. The personal name is composed of the elements 'Ead', prosperity, fortune, with 'gar', spear, and is first recorded in the Domesday Book of 1086 as 'Edgar', in 1095 as 'Aedgar', and in 1182 as 'Adger'. In early medieval records it is variously recorded as 'Edgar', 'Adger' and 'Agar'. A great number of different surnames have been generated by this personal name, ranging from 'Edgar', 'Eggar' and 'Egger' to 'Ager' and 'Eger'. The patronymic forms mean 'son of Edgar'. Frances Anne Eggers was christened at St. Martin-in-the-Fields, London, on the 26th April 1721. The first recorded spelling of the family name is shown to be that of Thomas Edgar, (witness), which was dated 1250, The Fees Court Rolls of Surrey, during the reign of King Henry III, 'The Frenchman', 1216 - 1272. Surnames became necessary when governments introduced personal taxation. In England this was known as Poll Tax. Throughout the centuries, surnames in every country have continued to "develop" often leading to astonishing variants of the original spelling.
