On the contrary, you've been a great help!
Every little bit of information may lead me to him. There is an outside possibility that he may have been brought back to New Jersey for burial. His son is buried there in the Churchyard cemetery where he once was the pastor.
His New Jersey obit also is very sparse, only a few sentences.
If his wife died ~1889 and he remained in Virginia afterwords then there is a good possibility that they are both buried there somewhere. We shall see.
Thank you for searching on my behalf.
