I have been researching the Mckabney's of Greene County also. James was a great- great grandfater. He was the father of Rebecca McKabney who married John Stone in Greene County in 1875 (12/22). To this union was born Jesse Stone who was my Grandfather. Jesse married Mary Turner and had 12 children. Jesse owned a farm in Chesterfield Illinois which is in macoupin county. The closest town is Carlinville Illinois which is the county seat of Macoupin. If anyone has anymore information it would be greatly appreciated.
