15[BBB]: There is a good deal of uncertainty about the three or four individuals, all named Jean, who follow next. There is no evidence to substantiate the existence of a Jean, as son of Robert and who, it is suggested, was born in 1270 and died in 1352. The first to appear in '1754' is Jean, Notaire du Roi, who, with his son Jean, was ennobled, as well as their posterity, by King Charles V of France, in September 1371, and is shown by the Letters of Nobility given to them and registered in the Chambre de Comptes of Paris. A copy of this entry was obtained in 1667, perhaps with the idea of using it in support of the family's claim to 'Noblesse', and it is reproduced in full in '1754'.
