The surname Rodger is of Scottish origin and derived from the Old English personal name Roger, which was introduced to Scotland by Norman settlers. The name Roger was in turn derived from the Old Norse name Hrodgeirr, composed of the elements "hrodr" (fame, glory) and "geirr" (spear). Therefore, the surname Rodger means "famous with the spear". It was originally found in the north-eastern lowlands of Scotland, particularly in Angus and Aberdeenshire, and is still a common name in these areas today.
