The family tree you found at your grandparent's house is probably the same as Marilyn had been working on. My sister has a copy and is going to make me a copy. I was just contacted by someone that says they have the "Motherload" on the Prisant family, so I am awaiting information from them. Apparently my great grandmother, Miriam Prisant was from a large family, so we have a lot more history to learn about, a whole new branch. I will forward the information as soon as I get it.
