James Hubert Theobald Charles Butler, 7th Marquess of Ormonde, MBE (19 April 1899 – 25 October 1997) was the son of Reverend Lord Theobald Butler and Lady Annabella Brydon Gordon.
Charles Butler was trained as a British Army officer at Sandhurst and received a commission as a lieutenant in the King's Royal Rifle Corps.
During the later years of his life, Lord Ormonde maintained an active role as President of the Butler Society.
Ownership of the Castle (which the Butler Family had not inhabited since 1935) had been transferred to the Town and People of Kilkenny by his predecessor, the 6th Marquess, in 1967.
The 18th Viscount Mountgarret, who succeeded his father in 2004 is understood to be the likely heir of the former Marquess' related title Earl of Ormond but has not successfully proven the claim.
