The Irish name O'Caullfields has been taken as synonym for many other names. The Gaelic form of the name O'Caullfields was generally Mac Cathmhaoil. The name Caulfield was used by people of the Irish names Ó Gamhna, Ó Caibheanaigh and Mac Conghamhna, and Mac Carrghamhna. 1 The Anglicized form of these last four Irish surnames is Gaffney, but for some obscure reason, this has often been changed to Caulfield.

Early Origins of the O'Caullfields family

The surname O'Caullfields was first found in Fermanagh (Irish: Fear Manach) in the southwestern part of Northern Ireland, Province of Ulster, where they held a family seat from ancient times. They were directly descended from King Colla da Crioch through the Maguires, Princes of Fermanagh.

Castle Caulfield is a large ruined house in Castlecaulfield, County Tyrone. At one time, the building was three stories high with large windows and tall chimney stacks. A wooden joist from the castle eludes to the age of the building as about 1282.

The Caulfeild Coat of Arms is still seen over the entrance. Nearby, Sir Toby Caulfeild, 1st Baron Caulfeild (1565-1627) built a house on the site of an earlier O'Donnelly castle. It was burned in the Irish Rebellion of 1641, but was rebuilt in the 1660s. Today Castle Caulfield is a ruin and declared a State Care Historic Monument.

Migration of the O'Caullfields family

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 O'Caullfields family in North America: Mary Caulfield, her husband Thomas and one child, settled in Charles Town [Charleston], South Carolina in 1822; Charlotte Caulfield settled in New Orleans in 1823.



The O'Caullfields 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: Deo duce ferro comitante
Motto Translation: God is my guide,and my sword is my companion.
