My g-g-grandfather, Saul (or Sol) H. Curtis(s) moved his family from Randolph County, Indiana to Logan County, Illinois between 1850 and 1860. My g-grandfather William Wesley Curtis married Eliza Ann Campbell on 27 December 1859 in Lincoln, Logan, Illinois. The 1860 and 1870 census shows them all living in Atlanta Township, Logan, IL. My g-grandfather moved his family to Cherokee County, Kansas between 1870 and 1880. Anyone have information on the Curtis or Campbell families or Logan County between 1850 and 1880? Thanks, Curt
