Overview[edit] It is usually anglicised as Reilly, Riley and O'Reilly. The original form of the name, Ó Raghallaigh, denotes "from/of Raghallach", the name Raghallach thought to be derived from the compounds ragh (meaning "race") and ceallach (meaning "sociable"). The Ó Raghallaigh family were part of the Connachta, with the eponymous Raghallach said to have died at the Battle of Clontarf
Battle of Clontarf
in 1014. The family became the kings of East Breifne, modern-day County Cavan and County Longford. The name is common and widespread throughout Ireland, ranked 8th most common in 1890 and 11th in 1996. The O'Reilly
Clan Chieftain to this day is at odds with the O'Rourke Clan Chieftain, because both clans viciously contest each other for the title Prince of Breifne. This was settled in 1994 when the Chief Herald of Ireland made the O'Rourke
Chief the Prince of Breifne, but the Office of the Chief Herald stopped granting courtesy titles to Gaelic Chiefs in 2003 (see O'Rourke). In 2017, with the election of the new O'Reilly
Chief, the rivalry has been re-kindled. People[edit] O'Reilly[edit] People with the surname O'Reilly
