The name Caldin comes from the Irish Gaelic name Ó Cathalain. The Gaelic versions of today's Irish names demonstrate a link to a proud, ancient past. The name is possibly derived from Cathalan, King of Farney slain in 1028, whose name means Little Charles. Cathalan was in turn descended from Coleman Mor, King of Meath and (the 133rd Monarch of Ireland). 1

Early Origins of the Caldin family

The surname Caldin was first found in County Roscommon (Irish: Ros Comáin) located in central Ireland in the province of Connacht, where they held a family seat from very ancient times.

Caillin (fl. 560), was an Irish saint, "son of Niata, descended from Rudraighe, whose grandson, Fergus Mac Roigh, flourished at the beginning of the Christian era. His mother was Deighe, granddaughter of Dubhthach, chief poet of King Laogaire in the time of St. Patrick. The authority for the history of St. Caillin is the ancient ‘Book of Fenagh,’ a series of poetical rhapsodies, written about 1400, a copy of which with a connecting narrative in prose was made in 1516. we may gather the following facts of St. Caillin's history from this curious repertory of ancient traditions: ‘The descendants of Medbh and Fergus, viz. the children of Conmac, Ciar, and Corc, grew and multiplied throughout Ireland. The children of Conmac especially were in Connaught.’ Those were the Conmaicne of Dunmor, kinsmen of Caillin's. Resolved to remedy the congestion of the population by killing each other, the Conmaicne would no doubt have carried out their plan but for the interference of St. Caillin. By the advice of an angel they sent messengers to him at Rome, whither he had gone for his education." 2

United States Caldin migration to the United States +

A massive amount of Ireland's native population left the island in the 19th century for North America and Australia in hopes of finding more opportunities and an escape from discrimination and oppression. A great portion of these migrants arrived on the eastern shores of the North American continent. Although they were generally poor and destitute, and, therefore, again discriminated against, these Irish people were heartily welcomed for the hard labor involved in the construction of railroads, canals, roadways, and buildings. Many others were put to work in the newly established factories or agricultural projects that were so essential to the development of what would become two of the wealthiest nations in the world. The Great Potato Famine during the late 1840s initiated the largest wave of Iris immigration. Early North American immigration and passenger lists have revealed a number of people bearing the name Caldin or a variant listed above:
