I came across your various messages about White Co IL and Posey Co IN families. I am researching several of the same-surname families.
At present I am trying to find out what happened to the family of Roswell (Rasnel) Howell and Emily Wells Howell. Roswell died in 1881 in White Co, but I have been unable to find the family on the 1880 census. They were living in Grayville from 1850 right through 1870. Emily is of a Posey Co family. One of her brothers married into the Eaton family ... and that family had at least one marriage into the Rutter family and several Davis marriages. The Wells and Davises are also connected.
The interconnected Davis families I am researching are those of Henry Davis b 1760 Lancaster Co PA, David Davis born bef 1772 and wife Elinor Moore, John and Richard Davis.
These families and those with whom they intermarried were all from the general Quaker/Primitive Baptist counties of Bucks, Berks, Chester, and Lancaster PA and from Hunterdon, Monmouth, and Somerset NJ, and Cecil and Harford Co, MD; most migrated via Loudon, Washington Co VA through various early counties in Kentucky and arrived in Posey Co between 1807 and 1820. Members of all families also found in Washington Co, IN. I also have several marriages into a Stephens family -- or several Stephens families that I haven't yet connected with each other.
Census data indicates Roswell was born in Virginia in 1814. His death occurred in 1881 in White Co, so they must have been somewhere in the area in 1880 (unless the rest of the family took off and left Roswell behind).
Have you run across this family at all in your research in White Co? I don't know that what I have on the other families would be of benefit to you, but I would be quite happy to share what I have on these people.
