William Colyear, 3rd Earl of Portmore


William Charles Colyear, 3rd Earl of Portmore was a Scottish peer, styled Viscount Milsington until 1785.
He was the second but only surviving son of Charles Colyear, 2nd Earl of Portmore, and his wife Juliana. He was styled Viscount Milsingtion in 1756 on the death of his brother David.
Milsington was educated at Eton and St John's College, Cambridge. In 1774, he unsuccessfully contested the constituency of Evesham as a Tory.
On 5 November 1770, he married Mary Leslie, second daughter of the 10th Earl of Rothes. Their children included:
The deaths of the couple's two daughters, Lady Mary and Lady Julia, in Bath, within three hours of one another on the same day in 1800, were the subject of a poem by Mary Young Sewell.
Like his father the earl, Viscount Milsington was a racehorse owner; he and his wife were regular racegoers. His grey mare, Tiffany, won the 50 l. weight-for-age race at Salisbury Races in 1780 and his horse Scarf ran in the 1781 Derby.
He succeeded as the 3rd Earl of Portmore on the death of his father in 1785. He died in London in 1823 and was succeeded by his son Thomas Charles Colyear, 4th Earl of Portmore.
