Conchobar Ó Muirdaig (died 1247) was Bishop of Kilmacduagh. Ó Muirdaig's surname is a common one in Ireland, variantly written as Ó Muireachaidh. The most prominent Connacht family of the name were natives of the kingdom Uí Maine (now east County Galway and south County Roscommon). The surname is now generally anglicised as Murray. An extract from the same annals, dated 1484, reads "Teige, the son of William, son of Hugh, son of Brian O'Kelly, was slain by Brian O'Kelly, his own brother, and William O'Murray, his own foster-brother, who were afterwards hanged by O'Kelly for their misdeeds."
