English: Recreation of seal reportedly used by Roger de Seymour (died circa 1299) of Penhow Castle, as reported by the Duchess of Cleveland in her Battle Abbey Roll (Wilhelmina, Duchess of Cleveland The Battle Abbey Roll with some Account of the Norman Lineages, 3 volumes, London, 1889, vol.1, Sent More[1]) thus:

"The Dukes of Somerset undoubtedly derive from William St. Maur, who in the thirteenth century possessed himself of Woundy and Penhow, where he took up his abode. "The church of Penhow was dedicated to St. Maur; their park there was called by their own name; and here likewise they had their castle, which continued in the family till Henry VIII.'s time."—Collins. The seal of his son Roger (who died about 1299) shows the Vol or Wings conjoined in Lure, still borne by his descendants, circumscribed Sigill Rogeri de Seimor". (Latin: sigillum, i.e. "seal of Roger de Seymour")

Image of Seymour Vol based on monumental brass of Nicholas Wadham (1508-1508) infant son of Sir Nicholas I Wadham (d.1542) of Merryfield, Ilton, by his 2nd wife Margaret Seymour (aunt of Queen Jane Seymour, 3rd wife of King Henry VIII), Ilton Church, Somerset.
