Barbara... Just today I ran across some old family documents that I hadn't seen before. I am a GG Grandaughter of Andrew Roll who shares a gravesite with Johannes Roll (lead me to assume a connection...) outside of Sauk City WI. I only have a handwritten accounting of Andrew's 9 children by my Great Aunt that is undated but she died in the 1960's. Five of those are listed as in Santa Clara, 1 unknown, 1 dead and 1 in Prairie du Sac WI and 1 in Sauk City WI (my G Grandmother). There is some interesting WI history involved!
