The name Cahalyn has undergone many variations in the time that has passed since its genesis. In Gaelic it appeared as "O Croinin," which derives from the word "cron," which meant "brown" or "dark." 1

Early Origins of the Cahalyn family

The surname Cahalyn was first found in County Cork (Irish: Corcaigh) the ancient Kingdom of Deis Muin (Desmond), located on the southwest coast of Ireland in the province of Munster.

Saint Crónán (died 640) was the abbot-bishop and patron of the diocese of Roscrea. His feasy day is April 28th. Mo Chua or Crónán mac Bécáin (died 637) was the founder of Balla, which later merged into that of Tuam, Ireland. Apparently the two were not related.

Temple Cronan is a ruined medieval chapel built near a holy well in the Burren, County Clare, Ireland. It dates from the 12th century and may have been originally built to serve as a pagan temple. The building looks to have been renovated in the 15th century, but it is thought that this stone structure replaced a wooden structure that is thought to have been founded by Saint Cronan.

Migration of the Cahalyn family

North America accepted thousands of Irish immigrants during the 19th century as their homeland suffered under foreign imperialistic rule. Although settlers from the early portion of the century came to North America by choice in search of land, by far the largest influx of Irish immigrants came to North America during the Great Potato Famine of the late 1840s. Many of these Irish families left the country destitute and in some cases suffering from disease. However, those who survived the long ocean voyage were especially vital to the development of industry in the United States and what would become known as Canada. Research of immigration and passenger lists has shown many early immigrants bearing the name Cahalyn: Johannes Cronin who settled in Philadelphia in 1738; followed by James Cronin in 1787; Charles, Cornelius, Daniel, Edward, Eugene, James, John, Michael, Patrick, Thomas, William Cronin, all settled in Philadelphia, Pennsylvania between 1817 and 1868.
