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

  • Facilitate communication amongst our clanfolk


This site is curated by Will Dougherty III under the direction of the Association of Ó Dochartaighs. ©2020 O'Doherty Heritage. Site Policies. I'd love to hear your thoughts on the site, answer your questions, or see you get involved! Email

Burt Castle

History of Burt Castle

Burt Castle, with its commanding view of Lough Swilly, was built during the mid-1500s as a stronghold to protect the southern portion of Ó Dochartaigh land. It was inhabited alternatively by the Ó Dochartaighs and by the English when the Ó Dochartaigh were allied to them. The holes in the castle are from practice shots fired by a British warship during World War I.

Visit Burt Castle!

  • The castle sits in the middle of a busy farm, privately owned by some friendly folk, so it's easy to miss visiting while taking a trip around the Irish countryside, unless you purpose to go there.
