Luther is a brother. Oliver & Levi may be cousins.
Rufus' obit wasn't too detailed. Place of death. County, state of birth, arrival in Indiana. Remains taken by rail to Union Station, but no cemetery given.
I haven't checked into the KY records for Dolly's obit or a death record. Early sources seem to agree on Sutton, but they may all be feeding off of one another. I've found a few errors on Jennison marriage and birth locations so far.
