The crest is that of Gower for Glanville Leveson Gower (1694-1754), who represented Newcastle-under-Tyne in Staffordshire, and later served as as Lord Privy-Seal and Lord Justice. During the Jacobite Rebellion he raised a regiment loyal to the King and for his service was created Viscount Trentham and Earl Gower in 1746.
Leveson Gower was married secondly to Penelope, daughter of Sir John Stonehouse, 7th Bt., in 1733, the same year that these salt cellars were produced. In 1736 he married thirdly Mary, daughter and co-heir of the 6th Earl of Thanet.
The Earls Gower and Thanet were both important de Lamerie patrons.
