I am searching for My great Grandmother Mary Gray's family she was married to Harry C Wetmore of Verona PA.
Her brother Philip was Godfather to my Gt Grandfather and his first name is my Grandfathers middle name. Philip and his wife witnessed my Grandfathers baptism in 1919. I am also curious as to John Gray (Purple Heart) buried at Mt Carmel Cemetery in Penn Hills b oct 26 1922 d nov 29 1998. My grandfather might be his first cousin.
I am wondering if he is Philips or another brother Grays son. It is reported that one of my family plots is occupied. We are not sure if it is Mary Gray, Her Husband Harry C Wetmore or quite possibly John as he is in the vicintiy of our plots.
