Early Origins of the McCahill family

The surname McCahill was first found in County Kerry and Tipperary as there are at least two distinct septs of the name. The first sept from County Kerry descend from the Heremon line of kings and were known as the Cahills of Connaught. The second sept claim descent from the Ir line of kings and were located at Corkashinny, or the parish of Templemore, Tipperary. This line further branched to the eponymous Ballycahill, Tipperary. Both branches descended from O'Connors, the Kings of Connacht, specifically "Cathal," also known as Conor na Luinge Luaithe, when anglicized means "Conor, the Swifter-Sailing Ship" [1] which may elude to the seafaring coat of arms used by the family.

United States McCahill migration to the United States +

The 19th century saw a great wave of Irish migrating out of their homeland in a great measure due to the oppressive imperial policies of the English government and landowners. Many of these Irish families sailed to North America aboard overcrowded passenger ships. By far, the largest influx of Irish immigrants to North America occurred with Great Potato Famine during the late 1840s. These particular immigrants were instrumental in creation of the United States and Canada as major industrial nations because the many essential elements such as the roadways, canals, bridges, and railways required an enormous quantity of cheap labor, which these poor immigrants provided. Later generations of Irish in these countries also went on to make valuable contributions in such fields as the arts, commerce, politics, and education. Extensive research into immigration and passenger lists has revealed many early immigrants bearing the name McCahill:

The McCahill 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: In Domino confido
Motto Translation: I trust in the Lord.
