I'm not sure specifically what the love stories within the Royal Oak Woman's Club the P3 are. It could be that members of the club have had various romantic encounters.

The life story of St Mary could be very diverse depending on which St Mary we are referring to. There could be many women named Mary in different historical and religious contexts. However, if we think of the Virgin Mary in Christian tradition, her story involves being chosen by God to bear Jesus. She was a young woman from Nazareth. Her life was full of significance as she was part of the most important event in Christian belief - the incarnation of God in the form of Jesus. She had to endure many hardships, from the initial disbelief of those around her when she became pregnant, to seeing her son go through his passion and death.
