- This talk was delivered to a history group in Ballybofey Library. It was of special interest to them in that Seoirse was able to prove very convincingly that Ardmiran was the original heartland of the Ó Dochartaigh clan before they transmigrated to Inishowen in the 1300s. Dunwiley (Dún Mhaonghaile) was their fort in Ardmiran, Maonghaile being one of the first in the clan to use the Ó Dochartaigh surname.
