Thames and Avon Branch of the Murray Club
Apprentice Boys of Derry
Colonel Mitchelburne, as Joint Governor during the Great Siege is credited with flying the Crimson or 'Victory Flag' from St. Columbs Cathedral in 1689, at the end of the Siege. He deposited the captured French flags in the Cathedral during the first commemoration service in 1692. He actually organised this commemoration of the Relief of Londonderry. In 1714 he formed the very first Apprentice Boys Club and pursued compensation claims for citizens of the Siege who had suffered so greatly. During the time he sought this compensation he even spent time in a London debtors jail.
Mitchelburne died in 1721 and is buried at Old Glendermott along with Adam Murray.
