Being that it was J Rutherford that helped to place a Pyramid monument at his grave site indicates he could have been associated with the Freemasons himself to a certain extent.

A cross and crown laid upon a cross pattée inscribed with "In Hoc Signo Vinces" resting upon downward pointing swords in saltire is often used to represent the Knights Templar.(The various symbols used allude to the orders of the body, though the cross and crown is often used alone as well.)
