Wesley Wagoner m. Nancy Sans in Illinois

Wesley Wagoner was my great-great-grandfather. He was married to Nancy Sans, both born in Illinois (probably around 1830). Their daughter was Mary Ann Wagoner, my grandmother, born 1850 in Jacksonville, Morgan Co., Illinois. She later married James Henry Johnson & lived in Missouri. Has anyone run across information on Wesley & Nancy? I can't find them listed anywhere. I would appreciate any info. Thanks.
