Donlevy

Arms of the MacDonlevy

The family's eponymous ancestor is Donn Sléibe mac Echdacha, who ruled as king of the Irish petty-kingdom of Dál Fiatach, as well as its over-kingdom, Ulaid, in the late 10th century. The power-base of the MacDonlevys was Dál Fiatach, a territory which spanned south from the Mourne Mountains north to the River Lagan; at times they exerted control over the entirety of Ulaid (eastern Ulster; present-day counties Down and Antrim).[2]

In the aftermath of John de Courcy's conquest of Ulaid in 1177, MacDonlevy's power was vanquished. As a result, the last-remaining members of the clan migrated to Tír Conaill (present-day County Donegal), whilst others went to Scotland.[2] In Donegal, they became the hereditary physicians (Old Irish: ollahm leighis) of the O'Donnells of Tír Conaill.[2] Indeed, since 1177, the MacDonlevys became renowned as a medical family and were among the foremost Irish medical families, employed across Gaelic Ireland and the Scottish Highlands and Isles.[2]

After the Battle of Kinsale in 1602, the sept migrated to the province of Connacht, where their name is now most common.[3][4] Some MacDonlevys in Donegal adopted the surname Mac an Ultaigh, meaning "son of the Ulsterman", which was anglicized as McNulty.[5]

• Cormac MacDonlevy (fl. c. 1460) was an influential medieval Irish physician and medical scholar, who advanced Irish medieval medical practice by, for the first time, translating seminal continental European medical texts from Latin to the vernacular. His translations provided the then-exclusively Gaelic language-speaking majority of Irish physicians with their first reference access to these texts.

The Annals note further that the branch of the MacDonlevy, who had been the physicians, still existed near Kilmacrenan, County Donegal in the early 17th century.
