They became the most prominent of the Ui Conaill Septs, who also had territory nearby in Co. Sligo in the north - west of the Connacht Province. The original Ulster O Donnell Family had its initial beginnings at Kilmacrenan, and began their rise to power during the Middle - Ages up until the 14th Century AD, which was then to last for another 300 years. Their last Chief was Niall "Garbh"- the Rough O Donnell, with their male line then continuing on down through his younger brother Hugh "Buidhe" - of the Yellow Hair" O Donnell to Aed / Aodh O Donnell who was at one time still living in Dublin in Co. Dublin in the north - east of Southern Leinster. The Ui Conaill Inauguration Stone of their Kings was at Doon Rock two miles west of Kilmacrenan, and up until 1540 AD none of their Kings or Chiefs was to ever pay homage to the English. In 1548 AD they founded a Franciscan Friary at Killydonnell / Cill O d - Ui Tomhrair in Co. Donegal where it’s bell was supposed to have ended up in Loch Swilly. *Aed "Ruadh" - The Red / "Red" Hugh O Donnell the nominated English 1st Earl of Tyrconnell held the lands in Ulster for 40 years, after his kinsman, Shane O Neill, was murdered by the Attainder (Off with his head) put on him by the Elizabeth 1st. "Red" Hugh O Donnell sided with his kinsman from the Heremonian Ui Cobhthaigh Dal Cuinn "Northern" Ui Niaill Cenel nEogain, ("Black" Hugh O Niall,) by negotiation and war. In 1597 AD "Red" Hugh O Donnell had his seat at the O Donnell Castle at Bally Shannon in Co. Donegal. The English had previously imprisoned him as a youth for years in Dublin Castle until he was eventually assisted by his kinsman "Black" Hugh "Dubh" O Niaill to escape and joined in with him to drive the English out of Ireland. He was subsequently done away with by a professional English assassin in Spain, and his brother, Rory O Donnell then took his place. He too was then forced to flee when an "Attainder" was also taken out against all of the Gaelic Ui Niaill leaders in Ulster. 3,500,000 acres of the territories of the "Northern" Ui Niaill Families were Confiscated by the English and non - Catholics were Planted there with the Irish Families driven off up above the 600" level to starve to death.
