William fitzStephen Barrett and his four sons (which included William Barrett Jr., and Phillip Barrett) followed ‘Le Gros’ to Ireland during the Cambro-Norman invasion. 

The Barretts of Pendyne were a powerful and influential family in Wales with many interests in Carmarthenshire and Pembrokeshire. The Barretts were followers of de Cogan in Glamorgan and under lords of Raymond ‘Le Gros’ de Carew in Pembrokeshire.  

In the wake of the 1170 Cambro-Norman invasion of Ireland, the Barretts of Pendyne fought under Milo de Cogan (Strongbow’s right-hand man in the invasion of Leinster) and were successful in battle. Milo de Cogan had secured considerable possessions in south and mid-County Cork and in turn awarded the Barrett’s that served under him a large portion of land.  After 1185, lead by John de Cogan (Milo’s grandson) the Barretts began to colonise the Lee Valley.  

The main Barrett holding originally lay around Glandore where the earliest known castle to be built by the Barrett Welshmen in Ireland still stands today. Glandore is from where the Barretts of Connaught also descend.
