Madison County Research

I am looking for any info on Samuel R. Cross and his wife Allie. They are on the 1900 census of Madison County and had been married for six years. No children were shown. There was a divorce but I don't know when. I know Samuel died in Benton County Arkansas married to another woman. According to family records Samuel caught Allie cheating on him. I would like to know who she was,anything about the divorce,were there any children,etc. They were married abt 1884.
