On Seymour’s wedding day in May 1818, Lady Williams Wynn reported that he was to marry Lady Charlotte Cholmondeley
en grande cérémonie at ten o’clock, under the auspices of [the] p[rince] r[egent], who is to give her away. I should not like to see my son receive a bride from such an unlucky hand, nor should I think my daughter’s virgin purity unpolluted in approaching the altar through so gross an atmosphere.
Williams Wynn Corresp. 207-8.
His father-in-law, a notorious lecher, was lord steward of the household and his uncle the 2nd marquess of Hertford, on whose interest he was twice returned for Antrim, was lord chamberlain, as well as the regent’s cuckold. Seymour, who was not in the end challenged at the general election of 1820, continued to support the Liverpool government silently.
