After de Hereford was given large territories by
Strongbow, he granted lands at what is now
Castlewarden, along with Wochtred (
Oughter Ard), both in County Kildare, to the Abbey of St Thomas in Dublin, leading to the foundation of
St. Wolstan's Priory. In 1219, the Norman landowners,
Warrisius de Peche, of the Manor of Lucan and Adam de Hereford, Lord of Leixlip, (Strongbow's right-hand man, and the Norman knight responsible for the construction of Leixlip Castle in 1172) granted to the brethren known as the order of the canons of St. Victor, the lands of St Katherine's, the
Prior John Warrisius, Bishop of
Meath Simon Rochfort and the Archbishop of
Dublin Henry de Loundres are mentioned in the documents. Among the lands bestowed by Strongbow on de Hereford was half the
vill of
Aghaboe. This land presumably included what is now the townland of
Rathpiper South in County Laois, where one of his descendants, Pipard, is believed to have been the builder of a castle less than one kilometre to the south-west of
Coolkerry Castle. Although the castle is no longer to be seen, it was marked on the first Ordnance Survey map and has been said to have been still standing in 1836. ==References==
