Christi, I hope you are out there somewhere. I see that this message was posted by you a few years ago. I MAY be able to shed some light on the background of the family you referenced. I believe that the Benjamin Aaron shown in the 1900 Missouri census in Butler County (Neely Twp.) is the son of Benjamin Aaron who lived in Hamilton County, Illinois for many years. He had a son, Benjamin F. Aaron, who was born about 1841-42. I have been trying to find out where this person went. I could not find him and his family after 1870 in the Illinois census. I now believe they moved to Missouri. Contact me at firstname.lastname@example.org. Hope I can help you out.
