Grant to William Henry Smyth (1788-1865). I think William’s father and grandfather were both born in New Jersey, and William’s grandson was the 1st Baron Baden-Powell (of Boy Scout fame). I think a part of the Moon is also named after him: https://en.wikipedia.org/wiki/Mare_Smythii
The grant includes as a charge in chief the insignia of a Knight of the Sicilian Order of St Ferdinand.
