Early Origins of the Croiley family

The surname Croiley was first found in Moylurg, in the County Roscommon, where they started as a branch of the MacDermots. It is from Teige, a Prince of Moylurg, down to Cruadhlaoch that the line of descent for the Crowleys begins. A junior branch of the Crowley family also emerged and moved to the area of Dunmanway, in the west of County Cork. They eventually became a distinct sept with their chief at Kilshallow, thriving while their parent family gradually withered. The majority of the Crowley family came to be found in the county of Cork, with three-quarters of the family being born there in modern times. 2

Migration of the Croiley family

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.
