Liberty of Thomas Court and Donore

[3] In 1195 the head of Hugh de Lacy, who had been killed in 1187, was sent by the Irish for burial at the Abbey of St. Thomas.

At this time the Abbey of St. Thomas Court held 56 rectories, 2,197 acres (8.89 km2) of land, 67 houses, 47 messuages and 19 gardens.

These possessions were distributed among several people, of which Sir William Brabazon (ancestor of the Earl of Meath) and Richard St. Leger were the major beneficiaries.

[5] On 31 March 1545 Sir William Brabazon was granted the lands of the Abbey, with all jurisdictions, liberties, privileges, and so on.

[7] The courthouse, located in Thomas Court Bawn, was used as a church in the 1760s while St. Catherine's was being renovated, and later was used as a Sunday school.

The officers of the manor consisted of a seneschal, registrar and marshal, who were appointed by the Earl of Meath.

[5] In 1760, the court house was refurbished to act as a temporary replacement or chapel of ease during the rebuilding of St Catherine's Church.
