I do know tht Sam Stewart had at least one child and as of 1988, she was still living. We had a dedication of the gallows as a state registered historic landmark upon its restoration that year and Sheriff Stewarts daughter and granddaughter were both present. In fact, the granddaughter assisted in the plaque unveiling.
I will go through my records and see if I can locate the granddaughters name and get you two in contact. I would rather not post her info here without permission, so feel free to email me at firstname.lastname@example.org
