Earl of Ruglen was a title in the Peerage of Scotland. Along with the
subsidiary titles Viscount of Riccartoun and Lord Hillhouse, it was
created on the 14th of April, 1697, for
Lord John Douglas-Hamilton, fourth (third surviving) son of William
Douglas-Hamilton, Duke of Hamilton, 1st Earl of Selkirk, and his wife Anne
Hamilton, 3rd Duchess of Hamilton.
The 1st Earl of Ruglen succeeded as 3rd Earl of Selkirk on the death of
his elder brother in 1739. The Earl's only son William, Lord Daer, died in
1742, so on the death of the Earl of Selkirk and Ruglen in 1744, the
Earldom of Selkirk passed to his great-nephew, while the Earldom of Ruglen
passed to his daughter, Anne, who had married
William Douglas, 2nd Earl of March.
On her death in 1748, the Earldom of Ruglen passed to her only child
William, 3rd Earl of March. He succeeded his first cousin once removed
Charles Douglas as 5th Marquess and 4th Duke of Queensberry in 1778.
The 3rd Earl died in 1810, and the Earldom of Ruglen became extinct,
while other titles passed to late Earl’s relatives. His second cousin
twice removed (Francis Douglas, 8th Earl of Wemyss) succeeded to the
Earldom of March, his fourth (and also third) cousin once removed (Sir
Charles Douglas, 5th Bt) succeeded to the Marquessate of Queensberry, and
his second cousin once removed (Henry Scott, 3rd Duke of Buccleuch)
succeeded to the Dukedom of Queensberry.
