William Henry Yelverton

William Henry Yelverton (5 December 1791 – 28 April 1884)[1] was a Whig politician who served as MP for Carmarthen Boroughs from 1832 to 1835.

[2] Yelverton inherited considerable lands and industry from his family and from his marriage to Elizabeth Lucy Morgan.

In 1811, Yelverton inherited the Blaiddbwll estate by an uncle to his mother, Captain John Parr.

According to Walker, Hendy Gwyn's family supported Longworth because, if her marriage to Avonmore had been confirmed as valid, the Viscount's children (from his second marriage) would have been illegitimate - and so their son, William Yelverton, would have been allowed to become heir to estates and viscountcy of Avonmore.

Walker accused William Yelverton of behavior so selfish, so base, so unnatural that it is hard to believe its existence.
