A freemason agrees in their obligation they have sworn not to be present at the making of a woman a Mason. This is, as stated by their Grand Lodge, one of the 'Landmarks of Freemasonry' and is deemed unchangeable.
In fact, no "mainstream" Lodge/Grand Lodge of Masons accepts women as members or will recognize (acknowledge) any lodge which does.
So that picture of your gran's school photo has no bearing on this.
For your information, I have been a Freemason for 20 years and although we do not have Ladies in our Lodges.Lady Freemasons do have their own Lodges and very good they are . In recent years they have been able to use the temples of the male lodges whereas before they had to meet in halls etc. If you check on any google site you will get a great deal of information about them.They also are a world wide organisation..(Patsyann's Husband)
Although ladies can setup their own lodges, they are not Freemasons. It would be like me and my friends setting up a gang calling ourselves The Girl Guides. We are girl guides only in our own eyes and would have no affiliation with the proper organisation.
Depends what country. In the US there are very few and a certain amount of hostility. in mainland Europe many more in both mixed and ladies' lodges, in the UK many ladies lodges and some mixed. Those lodges have no formal links with male lodges but informally sometimes borrow the lodge rooms and socialise.
