Oilibhéar

The origin of this name is still today quite uncertain. The theories include: 1) From the Germanic “Alfher” (from which Alvaro) or the Old Norse “Áleifr” from the Proto-Norse “*AnulaiƀaR” (from which Olaf). 2) From the Latin “ŏlīva” (olive, a symbol of peace, religious piety, or victory), referring to the fruit or the branch of the olive. 3) A third hypothesis, less accredited, is from the Mycenaean Greek “élaiwon (ἔλαιϝον),” Ancient Greek “élaion (ἔλαιον).” The names “Olaf” and “Oliver” are linked to the Latin root, but related to the Germanic and Norse, from (Alfher) and (Ólæifr). Saint Oliver Plunkett (1629–1681) was the Roman Catholic archbishop of Armagh and chief bishop of all of Ireland, who was the last victim of the papist plot.
