Herbert Windsor, 2nd Viscount Windsor
Herbert Windsor, 2nd Viscount Windsor, styled The Honourable Herbert Windsor until 1738, was a British landowner and Tory politician who sat in the House of Commons from 1734 until 1738 when he succeeded to the peerage as Baron Mountjoy and Viscount Windsor.
Windsor was the son of Thomas Windsor, 1st Viscount Windsor, by Lady Charlotte Herbert, daughter of Philip Herbert, 7th Earl of Pembroke. He stood unsuccessfully for Parliament for Bramber in 1734 but was instead elected unopposed for Cardiff, a seat controlled by his family. He held the seat until 1738, when he succeeded his father and entered the House of Lords.
Lord Windsor married Alice Clavering, daughter of Sir John Clavering, 3rd Baronet, a lady worth £60,000. They had several daughters. Windsor died in January 1758, aged 54. As he had no sons his titles died with him. Lady Windsor died in November 1776. One of their daughters, the Honourable Charlotte Jane Windsor, succeeded to the family estates. She married John Stuart, 4th Earl of Bute, who in 1776 was created Baron Cardiff in recognition of the vast estates in south Wales which had come into the Stuart family through his wife. In 1776 the Mountjoy and Windsor titles held by his wife's family were revived when Bute was made Viscount Mountjoy, Earl of Windsor and Marquess of Bute.
