You didn't include any dates, or approximate dates, for anyone in your query.I looked at your message history and none there, either.I went looking.Are you sure wife of Jonathan A. Wheeler was named Mariah?I have found a Margaret L.I would say from census records they were married about 1869/70 and Jonathan had children from a previous wife, can't read her name on the 1860 census. I don't know how much you may already have, so before I type all the census records I found, I thought I'd check with you first.
I notice John W. (father of Jonathan A.) has a son named Jubal.Do you know where in TN the family originated?Could they have a tie to the Jubal/Jubilee Wheeler in Jackson Co, TN? (My husband's Wheeler line.)That family also came down from VA.There is a bunch of Wheeler "cousins" working on that early line.
