Donnchath is Gaelic in Origin.

Donnchath is an archaic Old Irish form of the Gaelic name Donnchad/Donnchadh, built from donn “brown, dark (haired)” and cath “battle.” The ending -th reflects early orthography marking lenition of final -d; in standardized Irish and Scottish Gaelic the name appears as Donnchad (Old Irish) and Donnchadh (later Gaelic). The sense is commonly rendered “brown/dark warrior,” evoking a seasoned fighter distinguished by dark hair or complexion.

Use of the name was widespread among medieval Gaelic elites, notably borne by Donnchad mac Briain, king of Munster and son of Brian Boru, and by Donnchad mac Crínáin, known in English as Duncan I of Scotland. Variants include Irish Donncha/Donnacha, Scottish Gaelic Donnchadh, and Anglicized forms Duncan, Donough, and Donagh; nicknames Donnie and Donny are common in English. The spelling Donnchath is rare today but appeals in historically minded revivals.
