My dad's great aunt was Dova McCalvin. she was married to James Matney, who was dad's Grandmother Clara's brother. Dova was your Joe McCalvin's sister. Dad has some info about your McCalvin's shooting. You can contact Dad (Tom Henderson) at henderson1956@gmail.com.
Dad is working on my ancestry account and for some reason couldn't seem to reply to your message via Ancestry. FYI we will be visiting family in Huntington for Thanksgiving.
