"The derivation is from the Middle English (1200 - 1500) "egle", from the Old French "aigle", itself from the Latin "aquila", which, after the Norman Conquest of 1066 replaced the Olde English pre 7th Century word "earn". The second origin is locational and is a dialectal variant of the name "Oakley", from the place in Lincolnshire so called. The third source is also locational from the Norman placename "Laigle", in the province of Orne. Recordings from English Church Registers include the christening of John, son of George and Marie Eagle, on January 2nd 1596, at Repps with Bastwick, Norfolk, and the christening of Anne, daughter of William Eagle, in 1612, at St. James', Clerkenwell, London. The first recorded spelling of the family name is shown to be that of Ralph Egle, which was dated 1230, in the "Pipe Rolls of Yorkshire", during the reign of King Henry 111, known as "The Frenchman", 1216 - 1272." - The Internet Surname database
