McKibbyn History, Family Crest & Coats of Arms
The surname McKibbyn is derived from the name Gibb, a short form of the Norman personal name Gilbert. This name was originally derived from the name Gislebert, which is comprised of the Germanic elements "gisil," which means "hostage" or "noble youth," and "berht," which means "bright" or "famous." The name features the distinctive Irish patronymic prefix "fitz," which means "son of" in Anglo-French. This is derived from the Old French word "fils," which ultimately comes from the Latin word "filius," both of which mean "son." The Gaelic form of the surname McKibbyn is Mac Giobúin.
Early Origins of the McKibbyn family
The surname McKibbyn was first found in counties of Mayo and Limerick, where two distinct families arose shortly after Strongbow invasion of Ireland in 1172. The majority of the family hails from Mayo and were a branch of the great Burke family.
They were originally known as MacGibbon Burke. They gave their name to Ballymacgibbon in County Mayo. The Limerick FitzGibbon families are descended from John Fitzgerald, whose three sons became hereditary knights of Desmond in 1333.
Two branches of this family, known respectively as the knights of Glin and the knights of Kerry, remained Fitzgeralds. However, the third branch became known by the surname Fitzgibbon and was led by the White Knight, Maurice FitzGibbon, son of Sir Gilbert fitz John, eldest illegitimate son of John FitzGerald, 1st Baron Desmond. The territory of this branch lay in the southeastern corner of Limerick near County Cork.

Migration of the McKibbyn family
Ireland went through one of the most devastating periods in its history with the arrival of the Great Potato Famine of the 1840s. Many also lost their lives from typhus, fever and dysentery. And poverty was the general rule as tenant farmers were often evicted because they could not pay the high rents. Emigration to North America gave hundreds of families a chance at a life where work, freedom, and land ownership were all possible. For those who made the long journey, it meant hope and survival. The Irish emigration to British North America and the United States opened up the gates of industry, commerce, education and the arts. Early immigration and passenger lists have shown many Irish people bearing the name McKibbyn: Daniel, George, John, Michael, James, Nicholas, and Patrick Fitzgibbon who all arrived in Philadelphia between 1840 and 1865; Ann Gibbon settled in Virginia in 1660.
