Mac Fhirbhisigh


MacFirbis, also known as Forbes, was the surname of a family of Irish hereditary historians based for much of their known history at Lecan, Tireragh.
They claimed descent from Dathí, said to be one of the last pagan Kings of Connacht, and were thus one of the many families who sprang from the Uí Fiachrach dynasty. The progenitors of the MacFirbis family descend from Amhailgadh, whose brothers included Fiachra Ealg and Eocha Breac.

History

Based initially at Cong, the family may have been erenaghs prior to becoming historians and genealogists to the Ui Fiachrach Muaidhe and several other patrons. While this was their main function, they also appear to have served as poets and brehons to their patrons, possibly even musicians.
Among the earliest known members of the family were Amhlaoibh Mór mac Fir Bhisigh, Domhnall na Sgoile Mac Fir Bhisigh and Gilla Isa Mac Fir Bisigh, who died in 1301.
In the late medieval era the most well known was Giolla Íosa Mór Mac Fhirbhisigh fl. 1390–1418.
The Mac Fhirbhisigh, long after moving to Lecan, Tireragh, built Lacken Castle, now ruined, in Kilglass parish in 1560. Here they kept a school of poetry and history. They lost possession of the castle before 1625.
Fear Dorcha MacFhirbhisigh was noted as well-travelled in Scotland, showing how far afield members of the clan would venture in practising their art.
Dubhaltach MacFhirbhisigh compiled Leabhar na nGenealach, a massive compilation of Irish genealogies.
