John Davidson was my great-great grandfather. When Otto Faulkenburg was caught for a separate whitecapping incident, he implicated 13 other men in the lynching of John Davidson. Of the 13 who were accused, there was a Jacob L. Essary who was among the 3 indicted. I have been trying to research this by accessing old newspapers online. There are also court records available. Hope this helps, or points you in the right direction.
