13Ennobled by Charles I in 1341 and became 1st Baron Boileau. A certificate of the Patent of nobility granted to him and his posterity was given by the Bishop of Paris in 1667 and registered in the Chamber of Accounts there.

15[BBB] gives the following translation of this Patent:

"Extracted from the Register entitled 'The Register of Documents of the Chamber of Accounts of the Lord the King', begun at All Saints, 1362, and finished at 1st January, 1388.

Master Jean Boileau, Notary to the King, by the favour done to him by his (ie, the King's) letters, given in the month of September AD 1371, concerning his (ie, Jean's) nobility and that of Master Jean, his son, together with their posterity.

Issued and delivered on payment of the sum of 119 livres, 4 sous, 1 denier, which must be recovered by the Treasury, according to the schedule of the said Treasury given the 27th of October 1372, and returned to the said Master Jean.

Below is written: Compared with the original, signed, made an extracted as above by me, Conseiller, Secretary to the King, House and Crown of France, and his finances and Writer in the Chambre des Comptes, signed, Richer'. This fact is pronounced by the Notaries of the King at the Chatelet of Paris. Undersigned the 12th April 1667: Le Boucher, Levesque, signed with their official signatures."

[BBB] says that this Jean II could be the same as Jean IIa, and hence the nomenclature.
