Abbreviations

| dim. | diminutive |
| OI | Old Irish |
| MI | Middle Irish |
Note: Many of the Irish names are equivalents of the English by tradition and convention, not by any linguistic connection. For example, Donncha is the usual equivalent of Den(n)is, even though the words have completely unrelated histories. Also, many good Irish names do not appear here because they do not have common English equivalents.
