high king, which resulted in the kingdom of Osraige being officially dis-joined from the province of Munster. During his lifetime he is recorded to have even ruled over Dublin (from 872 to 888) and as far as the Orkneys due to his interconnections with his Viking neighbours. Land ingen Dúngaile (Princess of Osraige; daughter of king Dúngal mac Cellaig) Princess Land (sometimes spelt Lann) was a noteworthy figure in Irish politics during a critical time in Osraige's history, witnessing its dramatic rise to power under the rule of her brother Cerball mac Dúnlainge, in which she had a hand. She was married to the famous High King of all Ireland, Máel Sechnaill mac Máele Ruanaid (who reigned from 846 to 862) and gave birth to his formidable son Flann Sinna who was also High King from 879 to 916. (She is thus also the grandmother of High King Donnchadh Donn mac Flainn.) Gilla Pátraic mac Donnchada (King of Ossory from 976 to 996) King Cearbhall's descendant, Gilla Pátraic mac Donnchada, was king of Osraige from 976 to 996, and was the source of the patronymic Mac Giolla Phádraig. His wife was Máel Muire ingen Arailt, likely an Uí Ímair bride. He was an implacable opponent of Brian Boruma in his expansion over southern Ireland, being captured by him in 983 and released the following year. Later in his reign, he devastated Mide, and was killed in battle against Donnduban mac Imair, prince of Limerick, and Domnall mac Fáelán, king of Déisi. Donnchad mac Gilla Pátraic (King of Osraige from 1003 to 1039; king of Leinster from 1033 to 1039) In 1003, he killed his cousin, King Cellach. In 1016, he killed Donn Cuan mac Dúnlaing, king of Leinster, and Tadc ua Riain, king of Uí Drona. In 1022, he killed Sitriuc mac Ímair, king of Port Lairge (Waterford). In 1026, Donnchad spent Easter with the coarb of Patrick and Donnchad mac Briain. In 1027, he blinded his relative Tadc mac Gilla Pátraic. In 1033, Donnchad also took the kingship of Leinster and held the Fair of Carman to celebrate his over-kingship. In 1039, he led a hosting as far as Knowth and Drogheda., and he died the same year. Gofraid mac Arailt, King of the Isles, through his daughter Mael Muire, appears to have been the maternal grandfather of Donnchad mac Gilla Pátraic, the Osraige king of Leinster. Thus the
