The Scottish Rollo clan is said to be descended from Eric de Rollo, a relative of William the Conqueror. The aim of this Project to determine whether there is a common Y-DNA signature for all Scottish Rollos, (and whether that signature resembles that of any paternal line descendants of the dukes of Normandy). In time the project also hopes to unite branches of the family, and also to determine whether there is any relationship between the Scottish and Italian Rollos.
