Prior to the formation of female lodges Lady Elizabeth St. Ledger of Co. Cork is the only woman to be initiated into the Freemasons in the early 1700's.
She hid in a cupboard in order to eavesdrop on a meeting and was discovered,
she was held under lock and key for a number of days whilst the brethren decided whether to initiate her or kill her , they opted for initiation - quite lenient I would have thought !
