Milntown Castle: Milntown Castle was an early 16th-century castle which was situated near Milton, in Easter Ross, in the Scottish Highlands.  It was built by the Munro of Milntown family, a cadet branch of the Clan Munro.  In 1656, the castle and estate was sold to George Mackenzie, 1st Earl of Cromartie also known as George MacKenzie of Tarbet.  He renamed the estate New Tarbat after Tarbat Castle (now more commonly known as Ballone Castle), the family's original seat near Portmahomack.  Mackenzie had the Milntown Castle pulled down and only part of the basement survives.  He then replaced the castle with a new mansion built nearby.  When the new mansion was built, the old Milntown Castle was remodelled as part of the garden.  That mansion was itself demolished and in 1787 was replaced with a Georgian house (now known as Tarbat House) by his descendant John Mackenzie, Lord MacLeod.

She was transferred to the Home Fleet in December 1939, although she was badly damaged in a collision the following month, and required repairs that lasted until July 1940.  The ship joined Force H at Gibraltar in October, escorting the larger ships and various convoys until March 1941 when she was transferred to West Africa for convoy escort duties for a few months.  "Duncan" rejoined the 13th Destroyer Flotilla at Gibraltar in July and escorted several convoys to Malta during the rest of the year.  After a refit, she briefly returned to the 13th Destroyer Flotilla before joining the Eastern Fleet in the Indian Ocean to participate in Operation Ironclad in May 1942.  The ship was recalled home to be converted into an escort destroyer in late 1942.
