13Etienne Boileau is the first of family whose name is on records in 1253. He was appointed by Louis IX Grand Provost of Paris, then the most eminent Officer of (the?) 31 years before the French Parliament existed.
Lart is scornful of these first few generations, with no proofs of descent or marriages given.
[C-D, III, 384] “Etienne Boileau, Grand-Provost of Paris in 1250, a very important position before the Parliament existed. Louis IX, called Saint Louis, before his voyage to the Holy Land, chose him to reestablish justice. This magistrate, worthy of the highest praise, called the late President Hénault (?), travelled through the different regions of Paris, its communes and confréries, making many rules and regulations, which have since been copied and imitated, for the discipline of these communities, which had been formed a long time ago (?). Saint Louis seated(?) him by his side, when he was at the Castle, to encourage him and to show that he was strongly in support of his Justice reforms.”
It seems most likely that the Boileau bought their way into the nobility (and were originally drapers, according to Peter de Loriol). Etienne certainly existed (he is mentioned by Joinville) but his connection to the later Boileau line is unproven and probably fabricated.
