Hi. I am trying to get the achievement Mary of Lotharingia. I know Burgundy gets an event to get a female heir called Mary, but in my game i never got the event, Charles died and i decided to become a Junior Partner under Austria (because i integrate my dutch PU subjects) . I managed to form Lotharingia, i have no heir and i am waiting for one to appear. I looked through the game files for Lotharingia and i found that the chance of getting a female heir named Marie is 10%, but the question is: Do i need to have Marie (the heir from the event) to get the achievement or do i just have to hope that i get lucky to get a female heir in order to get the achievement ?
