Ayers/Ayres- Knox & Morrow Cty, OH

Does anyone know of my GGG Grandfather Enos M. Ayers born August 1, 1818 in Morrow County,OH who Married Margaret E. (Beveared)or (Bevard) on Nov. 18, 1841 in Knox County, OH. They moved to Illinois shortly after they married. Would love to know more about the family history in Ohio regarding his parents & siblings during this 1818 period and prior.
In Later years related siblings seem to use both spellings of Ayers/Ayres per gravestones. Also would like to know more about about his wife Margaret's family.
Thanks!
