Donnchadh 'Cime' Mág Samhradháin

Donnchadh ‘Cime’ Mág Samhradháin (anglicised McGovern) was chief of the McGovern Clan and Baron or Lord of Tullyhaw barony, County Cavan from 1258 to 1269.

His ancestry was Donnchadh son of Giolla na Naomh Mág Samhradháin (the Second) son of Giolla Íosa Mág Samhradháin (d. 1231) son of Giolla na Naomh Mág Samhradháin, the First, (fl. 1170) son of Muireadhach Mág Samhradhán(fl. 1130) son of Samhradhán (fl. 1100), who were all previous chiefs of the clan. Donnchadh's nickname 'Cime' is translated as 'a captive' perhaps meaning he had been a hostage in his youth. Alternatively there is a placename in Tullyhaw called Port Cime so he may have lived there .

On the death of the McGovern chief Brian Mág Samhradháin in 1258, Donnchadh took the chieftaincy.

Poem 2, stanza 7, by Giolla Pádraig mac Naimhin, written c.1290-1298, in the Book of Magauran describe Donnchadh as Donnchadh Cime of the royal stock.

Poem 26, stanza 26, written c.1339, in the Book of Magauran describes him as Donnchadh of Durlas, so his residence may have been called Durlas. He is also described therein as Donnchadh of Dún Uisnigh.

In 1269 he was murdered by his half-brother or step-brother Tomás Mág Samhradháin in an internecine struggle for the chieftaincy.
