In fact, the way it is spelled can sometimes be useful in tracing the locality of Irish ancestors. McGarrity is the common spelling for the name in County Tyrone, while Heraghty is found mostly in the coastal areas of Co. Mayo and Sligo. Geraghty is the usual spelling for the rest of the Republic of Ireland. Altogether there are well over twenty different spellings of the name.

Some settled in County Durham, Northumberland, Yorkshire, etc and remained there.
