DILLEY Family History

This interesting and unusual name is of French origin and is a topographical surname for a dweller on or near a small river in Brittany in the region of "Ille-et-Vilaine". The river name is "Illet", a tributary of the larger "Ille", which runs through Rennes, and is thought to derive from an ancient Celtic river name meaning trickling stream. Topographical names are some of the earliest names to be created, as topographical features, whether natural or man-made, provided obvious and convenient means of identification.
