Looking for Susan Eno of MO Ill

Not sure of last name spelling; might be phonetic. Possibly born in Mo., married Alex Belleville of St. Clair County, Ill. and had children, including Edward Refiles Belleville (b. East St. Louis, Ill., 1880), Anna Marie Belleville (b. East St. Louis, Ill., 1883) and Alexander Belleville (b. East St. Louis, Ill., 1885).
