By 1589, he was on more favorable terms to seek from the Earl of Ormond a lease of thirty-one years of the lands his family had occupied during the previous three centuries.
In 1596 the earl alleged breach of contract, with the result that Fearcorcha laid waste to the land.
He died sometime after 1611 and his heirs held their estates till the aftermath of the Irish Confederate Wars (1641–1653).
Feardorcha Ó Cellaigh married firstly to Catherine MacHugo, with whom he shared four daughters.
