The Marquess holds the subsidiary titles Baron Thynne, of Warminster in the County of Wiltshire, and Viscount Weymouth, both created in 1682 in the Peerage of England.

In 1641 his great-grandson Henry Frederick Thynne was created a Baronet, of Caus Castle, in the Baronetage of England (some sources claim that the territorial designation is "Kempsford in the County of Gloucester").

[2] Lord Weymouth died without surviving male issue in 1714 (one of his three sons, the Honourable Henry Thynne, represented Weymouth and Melcombe Regis and Tamworth in Parliament but had died in 1708, leaving only daughters) and was succeeded in the peerages (according to the special remainders) by his great-nephew, the second Viscount.

His second but eldest surviving son Henry, the 6th Marquess, represented Frome in the House of Commons as a Conservative.

The deal is simple: the wifelets get to hang out with Lord Bath in a jewel of a palace and in return he gets unlimited sex.

Lord Henry Thynne, second son of the third Marquess, was a Conservative politician and notably served as Treasurer of the Household from 1875 to 1880.

Lord Alexander Thynne, third son of the fourth Marquess, represented Bath in the House of Commons from 1910 to 1918.
