Spelling of names in Ireland in the 1800′s was unreliable and variations are often found and we have examples of Ford, Foard and Forde being used. Similarly we find Donlon, Donellan, Donnellan, etc. It seemed to depend on the person recording a birth or marriage. Many of the people in that era were not literate. Hence name and address spellings were often very varied.
It is thought the first Ford in the Ballynacurragh area was John Ford who came from Raheen, just West of Athenry, Co. Galway. He married A. Donnellan. They had 17 children and the eldest and youngest were Priests in Co. Galway.
