François Vaillant died in 1721, leaving three sons, Paul, Isaac, and François. The last, born in 1678 at Saumur, was apprenticed to David Willaume, the silversmith of St. James's, and took his freedom of the Goldsmiths' Company on April 17, 1701. He married Catherine Peirson, and is entered on the Rate Books of St. Martin's-in-the-Fields for 1710 and 1711 as of 4 Exchange Court, where he carried on the trade of a goldsmith, as a neighbour of Peter Archambo. The two elder sons continued in the business of their father (a bookseller), and it is Paul's name only, and later his son's, which appears on the Rate Books of St. Clement Danes from 1705 to 1768.
