The Wogan Brownes

Eustace's castle of Clongowes is mentioned in the State papers in 1538 in reference to the creation of Sir Thomas Eustace as Baron Kilcullen and Viscount Baltinglass. James Eustace, third Viscount Baltinglass, joined the Earl of Desmond in arms in the hope of placing Mary Queen of Scots on the English throne. The attempt failed and Baltinglass had to escape to Spain in 1583 where he died. One of his brothers was executed in Dublin, two others fled from the country and the family of Kilcullen lost its lands and titles.
