I didn't find any Minnie Scoville, Curtis's or Ronnie Ward in my tree. But I have a Kast. It goes as follows:
Warren Schoville m. Rachel Singles
James 1866-1949 m. Rachel Kelly
Henry Harrison 1879-1962 m. Carrie Shaw
Harvey 1882-1958 m. Martha L. Kast

Harley, Mary, Schelley, Otto, Alma, Naomi, Elinor, Vivian, Esther, Letha, Opal, Mary
PERL ALBERT 1885-1941 m. ELIZ ANN WARD 1889-1968

Fred, Archie, Freda, Dorvin, Dorothy, Harrison, Geraldine, Warren, ORVIN
Ther person with the Kast info would be Keith N. Schoville son of Harley Schoville. He also does research on this branch and we fill each other's empty spaces in at the family reunion. I will have to get his address and pass this info on for him.
