Dear Thomas, I am also researching one of the Miller/Muller/Mueller lines in Worth Township, Woodford County, Illinois. It goes back to the point that they emigrated from Wasserlos, Germany in 1840-1841 to the area of Lourdes in Woodford County, Illinois. The initial party was Nikolaus Muller, his son, Michael and his wife, Anna Maria (nee Streit) Muller, and their infant son, Peter. Peter married Katharine T. Bergmann, daughter of Kilian and Klara (nee Wilz) Bergmann, in Woodford County, IL, and I believe they had 13 children. I do not have any record of a Lavinia or Lavina Miller, however. Kevin
