I don't have any more information on the shooting. The report was given to me by a researcher several years ago, and I have since lost contact with him. This was early in my genealogical research and through computer gliches and other changes, I no longer have his address.
Actually, I am somewhat skeptical of the report and regret posting it to this forum. James' father, John (aka "Gus") Offill reportedly died in 1805-1810. James was only 11 years old in 1810. John could have died somewhat later, but, the chances of finding documentary information that long ago are very small.
