The records stop with 1944. I think additional records will be added in November 2014.
I tried finding Elizabeth/Lizzie using Butler/Buttler. There was only one Lizzie Butler who died before 12.30.1922 with "married." (There is one widowed Lizzie Butler who died in Philly but the information doesn't match.) She died in a Pittsburgh hospital and is buried in Frederickstown, PA according to the death certificate. It probably should read Fredericktown, Washington County, PA. Lots of rubber stamps for information by the hospital or funeral home. Maybe this Lizzie wasn't born in PA. Unless she was removed to Hewitt Cemetery later, she probably isn't your Elizabeth/Lizzie. But a removal could explain why the caretaker has no dates.
For what it's worth, attached is the certificate.
