Hello, Betty Ann:
I live in PA now or would be glad to go to St. John's to look for the grave. Off the top of my head I can't think of anyone in that area who would do it for you. I've been living in PA for the past 38 years and don't have many friends who still live in that area. I suggest you post a request and see if anyone answers you. There must be someone in Orange or West Orange who would do it for you.
Sorry I can't be of more help.
