McCrosky History, Family Crest & Coats of Arms
The original Gaelic form of the Irish name McCrosky was written as Mac an Chrosain, which is derived from the word cros, which means cross.
Early Origins of the McCrosky family
The surname McCrosky was first found in Leinster, where they held a family seat at Ballymacrossan on the border of Leix and Offaly. There they were an off-shoot of the notable Clan O'Moore which was the leading sept of the 'Seven Clans of Leix'. In Gaelic the surname is "Mac an Chrosain," but more frequently seen in the English form "Crosby" or "Crosbie" which was listed as early as the early 1600s.

McCrosky migration to the United States
The 19th century saw a great wave of Irish migrating out of their homeland in a great measure due to the oppressive imperial policies of the English government and landowners. Many of these Irish families sailed to North America aboard overcrowded passenger ships. By far, the largest influx of Irish immigrants to North America occurred with Great Potato Famine during the late 1840s. These particular immigrants were instrumental in creation of the United States and Canada as major industrial nations because the many essential elements such as the roadways, canals, bridges, and railways required an enormous quantity of cheap labor, which these poor immigrants provided. Later generations of Irish in these countries also went on to make valuable contributions in such fields as the arts, commerce, politics, and education. Extensive research into immigration and passenger lists has revealed many early immigrants bearing the name McCrosky:
