Does the constitution specifically allow a son of a Mason to be initiated at a tuner age than usual?

Yes, the constitution allows for the sons of Master Masons to be proposed for initiation at a younger age. Specifically, Rule 133 states: "No person shall be made a Mason while under the age of twenty-one years except in the case of sons of Master Masons under Grand Lodge, who may be proposed at any time after attaining eighteen years of age." This provision recognizes the unique connection and legacy of Masonic families, allowing sons of Masons to join the fraternity at the age of eighteen, rather than the standard minimum age of twenty-one.
