My great-great-grandfather is the same John Bear, buried in the Old Kingsport Presbyterian Church Cemetery, in Kingsport Tennessee -- direct line. My grandmother, was Bertha Mae Bear (1909-1982), whose father was Charlie Bear (1880 or '81 - 1960), whose father was John Bear (1843-1918). John married Mary Polly Bear (who is buried in same cemetery) in 1869, at the age of 26. I have many ancestors buried in that cemetery.
I have John Bear's Death Certificate and it states that his parents were James Bear and Bettie Myers.
I'd like to exchange info with someone on this Bear lineage, as some of you may have some info that I am still missing.
