Gauslin
Gauslin is a surname of French origin. It is believed to be a variant of the given name Gautier, which itself is derived from the Germanic name Walter. The name Walter is composed of the elements "wald" meaning "power" or "rule" and "heri" meaning "army". Therefore, Gauslin, as a derivative, likely carries a similar meaning. The surname may have originated as a patronymic, indicating "son of Gautier" or "descendant of Gautier".
The distribution of the Gauslin surname is primarily concentrated in France, particularly in the Normandy region.
