Tim, If your James Wilkinson was married in 1825, he would have been born about 1800-1805, making him 56-61 when he committed the murder.Is this correct?
My James Wilkinson is actually John James Wilkinson b 1831 in Kentucky to William Wilkinson and Jane ?, apparently.
His companion in crime was named John Allen, who, if he and James Wilkinson are my relatives would have been barothers-in-law.But my Wilkinsons and Allens were in Greene County, IL. The dates don't seem to match yours. And though my John James Wilkinson's father was a William, his mother was Jane.
However, I do have his youngest daughter dying in Carollton.Looks like a good deal more research may be required on this family.Do you have documents that will clarify who was whom?
