LILES Family History

This interesting and unusual name is of French origin, and has two possible, related sources. The first of these is Norman, introduced into England after the Conquest of 1066, and is a topographical surname for someone who lived on an island, derived from the Olde French and Middle English word "isle", from the Latin "insula". The modern surname, found as Lisle, Lile(s), Lyle, de Lisle, De L'Isle and de Lyle, is the result of the French definite article "le" becoming fused with "isle". The surname may also be locational from the French form of "Lille", which also derives its name from the Olde French "isle".
