Just found an article that’s apparently been up for a while on the Academy of Saint Gabriel where the illustrious Solveig Throndardottir discusses family crests: A Roll of Japanese Armory. It’s short, but it features several pages of mon from the Battle of Sekigahara in 1600, which is handy for those seeking a wider selection of Azuchi-Momoyama period (1573 to 1603) mon.
