Rudraige was the name of two other figures from Irish mythology, one a son of Partholón, who led the first settlement of Ireland after the Flood, the other a Milesian High King of the 2nd or 3rd century BC.
In medieval texts they are also referred to as the Clanna Rudraige (modern spelling: Clanna Rudhraighe, anglicisation: Clanna Rury) meaning "descendants of Rudraige".
