Early Modern History


During the English conquest of Ireland in the 16th century, the Northern Uí Néill, among whom were the Ó Dochartaigh, were the last to submit. When they finally did, it was often used as a tool against opposing clans or to buy time to prepare for another rebellion. Near 1600 A.D., the Ó Dogherty and their comrades-in-arms the McDevitt were strengthening their fortresses, secretly making arms deals to import modern weaponry, and preparing to receive thousands of Spanish soldiers to assist with their rebellion against the English, but the Spanish didn't deliver. To protect his clansmen and their lands, with help of the McDevitts, the teenaged chieftain, Cahir Ó Dogherty, was allied to Sir Henry Docwra the English governor of Derry, who saw him as a son. After Cahir saved Docwra's life in battle, he was knighted and found incredible favor with the English both in Derry as well as in the royal court at London. However, a new governor, Sir George Paulet, a politically incompetent man who coveted the Ó Dochartaigh lands, provoked the clann into rebellion. Sir Cahir Ó Dogherty and his men burned the English fortification of Derry to the ground on the 19th of April 1608 and then fought bravely against the powerful English forces. Sadly, after 77 days, Sir Cahir was shot, drawn and quartered, and his head displayed on a pike by the English at Dublin Castle. The heroic Sir Cahir Ó Dogherty was the last remaining Gaelic chieftain of Ireland. With the last stronghold of ancient Gaelic society fallen in Ireland, this paved the way for the Ulster Plantation and subsequent conquest, though his sister Rosa returned from Spain to plan another rebellion in 1641. Despite hundreds of years having passed, our ancestral homeland is still as stunningly beautiful as in centuries bygone and the Gaelic culture has been revived in many areas of Donegal.



The O'Doherty Heritage website is designed to be your place for all things Ó Dochartaigh. Whether your name or ancestry is from a Doherty, Dougherty, Daugherty, Docherty, Dogherty, if your family used another spelling of our name, or if you're from one of our related Donegal families, such as the McDevitt/McDaid, McBride, McConlogue, or others–we welcome you to the O'Doherty Heritage website!

The vision of the O'Doherty Heritage is "Telling our story, uniting us together." This was the same vision of our ancestors, the Ó Dochartaigh patriarchs, when they established our Clan motto, Ár nDúthchas–which means 'Our Heritage'. Below are the goals of O'Doherty Heritage:


  • Share our heritage with our entire Clan

  • Research, document, & bring our history to life

  • Curate a digital Clan genealogy research library


  • Encourage quality genealogical research

  • Promote clan identity and pride in our heritage
