Show ContentsKeiran History, Family Crest & Coats of Arms

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 Keiran 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 Keiran family

The surname Keiran 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.

United States Keiran migration to the United States +

To escape the religious and political discrimination they experienced primarily at the hands of the English, thousands of Irish left their homeland in the 19th century. These migrants typically settled in communities throughout the East Coast of North America, but also joined the wagon trains moving out to the Midwest. Ironically, when the American War of Independence began, many Irish settlers took the side of England, and at the war's conclusion moved north to Canada. These United Empire Loyalists, were granted land along the St. Lawrence River and the Niagara Peninsula. Other Irish immigrants settled in Newfoundland, the Ottawa Valley, New Brunswick and Nova Scotia. The greatest influx of Irish immigrants, however, came to North America during the Great Potato Famine of the late 1840s. Thousands left Ireland at this time for North America and Australia. Many of those numbers, however, did not live through the long sea passage. These Irish settlers to North America were immediately put to work building railroads, coal mines, bridges, and canals. Irish settlers made an inestimable contribution to the building of the New World. Early North American immigration records have revealed a number of people bearing the Irish name Keiran or a variant listed above, including:

Keiran Settlers in United States in the 19th Century
  • James, Patrick and Thomas Keiran, who arrived in Philadelphia between 1840 and 1860
  • John Keiran, who arrived in St Clair County, Illinois in 1864 2
  • Owen Keiran, aged 45, who landed in Mobile, Ala in 1868 2


The Keiran 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.
