Show ContentsCrowly History, Family Crest & Coats of Arms

Irish names tend to vary widely in their spelling and overall form. The original Gaelic form of the name Crowly is "O Cruadhlaoich." This is derived from the words "cruadh," which means "hard," and "laoch," which means "hero." 1

Early Origins of the Crowly family

The surname Crowly 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

United States Crowly migration to the United States +

Death and immigration greatly reduced Ireland's population in the 19th century. For the native Irish people poverty, hunger, and racial prejudice was common. Therefore, thousands left their homeland to seek opportunity in North America. Those who survived the journey and the quarantine camps to which they arrived, were instrumental towards building the strong developing nations of the United States and the future Canada. By far, the largest influx of Irish settlers occurred with Great Potato Famine during the late 1840s. These were employed as construction or factory workers. An examination of passenger and immigration lists has shown early immigrants bearing the name Crowly:
