Etymology of Keiron

What does the name Keiron mean?

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 Keiron as Ó Ciarain or Mac Ciarain. These names are derived from the word "ciar," which means "black" or "dark brown." 1

Early Origins of the Keiron family

The surname Keiron was first found in County Mayo (Irish: Maigh Eo) located on the West coast of the Republic of Ireland in the province of Connacht, where they held a family seat from ancient times.

Keiron Spelling Variations

The recording of names in Ireland during the Middle Ages was an inconsistent endeavor at best. Since the general population did not know how to read or write, they could only specify how their names should be recorded orally. Research into the name Keiron revealed spelling variations, including Kieran, O'Kieran, Keiran, Keighran, O'Keiran, Kerin and many more.

Migration of the Keiron family

A great mass of Ireland's native population left the island in the 19th century, seeking relief from various forms of social, religious, and economic discrimination. This Irish exodus was primarily to North America. If the migrants survived the long ocean journey, many unfortunately would find more discrimination in the colonies of British North America and the fledgling United States of America. These newly arrived Irish were, however, wanted as a cheap source of labor for the many large agricultural and industrial projects that were essential to the development of what would become two of the wealthiest nations in the western world. Early immigration and passenger lists indicate many people bearing the Keiron name: James, Patrick and Thomas, who Keiran arrived in Philadelphia between 1840 and 1860; John and Thomas Kieran settled in Philadelphia between 1858 and 1868. In Newfoundland, William Kearon, from Tallon, Waterford county, Ireland, was married in St. John'.

The Keiron 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.
