Dunaway is from Donnchaidh, the Ulster Irish version of Donnchadha. https://www.libraryireland.com/names/macd/mac-donnchadha-mac-donnchaidh.php https://www.howtopronounce.com/donnachaidh/ https://www.abair.tcd.ie/en/ (accept cookies, type the name 'Donnchaidh', select 'Gweedore' and 'Unit Selection', then 'Say It!') https://forvo.com/word/donnchadha/ All spelling variations are welcome. If your Surname is missing and should be included, we'll be glad to add it. Please visit our website and add your family to the Patriarch Page. The Dunaway Family Project exists to assist researchers with finding their heritage through the sharing of information and dna testing - and to that end, as an adjunct to the Results groupings, members are encouraged to communicate via the Activity page. Though our Project is still small, we have positively identified three distinct branches of Dunaways - two connecting to the O'Donoghue Septs of Munster; and one to those of Co. Cavan. To which do you belong? Or do we have more branches to find?
