John Butler, 15th Earl of Ormonde

John Butler (died 1766), known as John Butler of Kilcash, a member of the Irish landed gentry, was de jure 15th Earl of Ormond and 8th Earl of Ossory. He did not assume these titles as he thought them forfeit by the attainder of the 2nd Duke of Ormond. He did, however, inherit the Ormond estate from the 1st Earl of Arran through Arran's sister Amelia. In 1791, the title of Earl of Ormond would be successfully claimed by his cousin, the 17th Earl.
