The established crests were from the history of the families, ie, Bourgeois, Landry, Comeau (various spellings)Savoy (Savoie), Blanchard, etc. The Broussard lineage dates back to Kings of france; although, no connection to date of Francois and his parentage. I do not have complete listings of Crests, that would require research by individual family histories. St Anne's University has photos, but not all are correct: the crest they depict for Broussard (Brossard) is actually the Crest for Bousse Family. I pointed that out to them during 1999 Congres Mondial de Acadiennes 1999 in Louisiana, and they were suppose to correct the error, but they did nothing. Additionally, the Landry Family has 13 Crests listed in official publication, so the family had to locate the crest for their family by area of France they came from. I would note to you also that there are many "old wives tales" concerning Francois Broussard. Because of an error in translation of a document he was "tagged as Jean Francois, the Jean was an error, as pointed out by Stephen White of Moncton University (likely the leading Acadian Genealogist today). Second, he was purported to have been born in France, and sailing to Acadia on ship L'Oranger; this was also refuted by Stephen White. That ship was supposed to have sailed from France to Acadia in 1654, but French Maritime records show no such sailing to Acadia; later it did sail to dominican republic, but there were no Broussard (Brossard) aboard. In 1653, a year prior to purported sailing, Francois is recorded in Canadian Archives as buyer of clothing from widow of a drown trapper. I recall someone having lineage of Broussard Family back to Adam, yet I could not find a passenger manifest for Noah's Ark to confirm that fact. Likewise, some attempted to link Francois to the Brossard Family of Quebec, and jumped upon birth of a Francois to that family; they forgot to read entire passage, wher it stated that Francois died at age 13; hard to marry, have 11 children, and die at 13, even for a Broussard. Best advice I can offer, is to weigh each piece of information, check and double check it, and above all, don;t rush to judgemnet!
