I remember seeing a Web 1.0ish website with a great chart with ALL of the relationships described in Mesechet Yevamot. This website also had a click through tour of diagrams of the Beit Hamikdash. I believe that it is someone's personal web site (i.e. it has some of their research on it too.) Does anyone know which website I'm remembering? I am going to start Yevamot soon, and it would be a great help. Thanks in advance.
