Cooper family S. central Ohio to Marshall Co., Illinois

My ancestral grandfather, John Ridgeway, md Mary Ann Cooper, Ross Co., Ohio about 1819. Her family removed with the Ridgeway family, possibly the Spar family and others to the Illinois area of Peoria Co.& Marshall Co. Jeremiah Cooper among those, and I believ a Abner Cooper. John and Mary Ann (Cooper) had children, and Mary Ann apparently died about 1831, probably in Peoria Co. John then married Ann McGee there in 1832. They moved to adjacent county, Marshall Co, where all are found in the 1850 census. Jeremiah Cooper died in a blizzard, and Jeremiah, Jr died in an epidemic abt 1852. John Ridgeway died in 1852, and his widow, Ann, was made guardian of the infant daughter of Jeremiah Cooper, Jr. I am seeking information, (or clues) about Ann McGee. Anyone with information about this Jeremiah Cooper of Ohio, may have allied information about my Ridgeway and McGee line.My gmail address is Cbrees2421.Carol Ashby
