My husband grew up in Mason, Mi. He does remember the name of Childs...Might I suggest a call to the MASON Public Library ---or the County clerk .I believe Mason is the county seat .Ask if there is a local historian; if they do not know who is the present caretaker in charge of records of cemetery. AND hope you get a chatty answerer. Another thought---a local funeral home might be able to answer who they deal with when opening a grave...etc Florence NJ
