GALLACHER Family History
This famous surname is of ancient Gaelic origin. It derives from the medieval Irish surname O'Gallchobhair, meaning the male descendant of Gallchobhair. This was a personal name composed of the elements "gall", meaning foreign, and "cabhair", help, suggesting that the original name holders were foreign mercenaries, possibly Welsh. The O'Gallachers belonged to County Donegal and are one of the Cineal Connall line. That is one of the families descended from Connall Gulban, a son of Niall of the Nine Hostages, given as being a 4th century King of Ireland.Who have we missed?
