Early Origins of the MacColgan family

The surname MacColgan was first found in County Derry, also known as Londonderry where they claim descent from the O'Conors (Faley) through Cumasach, brother of Aeneas, having derived their surname from the Irish "colg" which means "sword," thus the name Colgan was a "swordsman," a quo Clann Colgain. 1

The MacColgan Motto +

The motto was originally a war cry or slogan. Mottoes first began to be shown with arms in the 14th and 15th centuries, but were not in general use until the 17th century. Thus the oldest coats of arms generally do not include a motto. Mottoes seldom form part of the grant of arms: Under most heraldic authorities, a motto is an optional component of the coat of arms, and can be added to or changed at will; many families have chosen not to display a motto.

Motto: Virtus probata florescit
Motto Translation: Tried virtue flourishes.
