Gaelic, otherwise known as Early Modern Irish, was used in Ireland from around the year 1200 until the 18th century. It is from this language that we found the first references to the name Kieran as Ó Ciarain or Mac Ciarain. These names are derived from the word "ciar," which means "black" or "dark brown." 1

Those who lived to see North American shores were instrumental in the development of the growing nations of Canada and the United States.

The Kieran 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: Fidens et constans
Motto Translation: Stand firm on trust.
