Richard Butler, 1st Earl of Arran

Richard Butler, Earl of Arran (1639–1686) was Lord Deputy of Ireland from 1682 to 1684 while James Butler, 1st Duke of Ormonde, his father, the Lord Lieutenant, was absent in England. He sat in the Irish House of Lords as Earl of Arran and in the English one as Baron Butler of Weston. When William Howard, 1st Viscount Stafford was accused of treason during the Popish Plot, Arran braved the anti-Catholic hysteria and voted not guilty.
