Where did the Irish Kirwan family come from? What is the Irish Kirwan family crest and coat of arms? When did the Kirwan family first arrive in the United States? Where did the various branches of the family go? What is the Kirwan family history?

Many variations of the name Kirwan have evolved since the time of its initial creation. In Gaelic it appeared as O Ciardhubhain, which is derived from the words "ciar" and "dubh," both of which mean "black."


Those scribes in Ireland during the Middle Ages recorded names as they sounded. Consequently, in this era many people were recorded under different spellings each time their name was written down. Research on the Kirwan family name revealed numerous spelling variations, including Kirwan, O'Kirwan, Kerovan, Kyrvan, O'Quirivan, Kirwin, Kerwin, Kerwan and many more.

First found in County Galway (Irish: Gaillimh) part of the province of Connacht, located on the west coast of the Island, where they held a family seat from ancient times.

During the 19th century thousands of impoverished Irish families made the long journey to British North America and the United States. These people were leaving a land that had become beset with poverty, lack of opportunity, and hunger. In North America, they hoped to find land, work, and political and religious freedoms. Although the majority of the immigrants that survived the long sea passage did make these discoveries, it was not without much perseverance and hard work: by the mid-19th century land suitable for agriculture was short supply, especially in British North America, in the east; the work available was generally low paying and physically taxing construction or factory work; and the English stereotypes concerning the Irish, although less frequent and vehement, were, nevertheless, present in the land of freedom, liberty, and equality for all men. The largest influx of Irish settlers occurred with Great Potato Famine during the late 1840s. Research into passenger and immigration lists has brought forth evidence of the early members of the Kirwan family in North America:

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: Mon Dieu, mon Roi, et ma patrie
Motto Translation: Mon Dieu, mon Roi, et ma patrie.
