Glad that helped Charlie. Although I can't find anything about Judith Ham's death. Also don't know who Rebecca Arno is that was born in 1781. She can't be a grandaughter of John's. She's buried with Hiram's group.
I have not been able to find anything though about John Arno's second wife? Just the third one, the stone that you saw was broken off is her's and her daughter (not his) is buried with them also.
