There is a source no one stopped to think and look. I am working on photos of gravemarkers for Centerville City Cemetery in Centerville, Utah One thing I can tell you.. There are MISSED ones even recent ones. Because I constantly checking nFS, WorldConnect, census for maiden surnames. Often I would turn up missing children and spouses in gravemarkers not found elsewhere. And often I would find the information to be incorrect in newFamilySearch because of wrong burial places. One example has a lady buried in western New York when in fact she did died there but was brought back to Massachusetts to be buried with family. That was 1828. A good source to check for them is http://gpp.jlconsulting.com/ 23 states now. W. David Samuelsen (running Utah, Oregon, New York and Massachusetts)
