Gilla Cellaig Ó Ruaidín, aka Gilbert Ó Ruane, Bishop of Kilmacduagh, died 1204.
Ó Ruaidín (Rooane, Ruane, Rowan) was the third apparent member of his family to serve as Bishop of Kilmacduagh, and the last. His family were one of two apparently unrelated families, based in what would become County Mayo and County Galway, respectively. The Galway family was of the Ui Maine.
He was elected before 5 May 1248 and received possession of the temporalities after that date, dying before 10 November 1253. He was also known as Gillebertus or Gilbert, a Latinisation of his forename.
