Nicholas Cusack

Nicholas Cusack (died 5 September 1299) was a thirteenth-century Bishop of Kildare and member of the Franciscan Order.

[3] He warned that the monks were meeting with the native Irish rulers in secret and assuring them that it was a lawful and Godly act to attack the English colony.

The following year he and the Bishop of Meath, Thomas St Leger, were chosen to collect the papal tax granted by Pope Nicholas III to the King for the relief of the Holy Land.

[2] In his last years, he clashed several times with William de Vesci (d. 1297), the Justiciar of Ireland, and his subordinate official Thomas Darcy, Seneschal of Kildare.

The clashes were over the extent of William's private rights and privileges as Lord of the liberty of County Kildare, which he had inherited from his mother, Agnes de Ferrers, who was one of the Marshal co-heiresses.
