McGibbony History, Family Crest & Coats of Arms
The surname McGibbony 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 McGibbony is Mac Giobúin.
Early Origins of the McGibbony family
The surname McGibbony 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.

In the mid-19th century, Ireland experienced one of the worst periods in its entire history. During this decade in order to ease the pressure of the soil, which was actually depleted by the effects of the previous years' grain crops, landowners forced tenant farmers and peasants onto tiny plots of land that barely provided the basic sustenance a family required. Conditions were worsened, though, by the population of the country, which was growing fast to roughly eight million. So when the Great Potato Famine of the mid-1840s hit, starvation and diseases decimated the population. Thousands of Irish families left the country for British North America and the United States. The new immigrants were often accommodated either in the opening western frontiers or as cheap unskilled labor in the established centers. In early passenger and immigration lists there are many immigrants bearing the name McGibbony:
