Hello. I am a Librarian in New Jersey and have been doing family research since early 2007. We finished taking inventory of Willow Grove Cemetery in New Brunswick, NJ as part of a grant awarded to the New Brunswick Library. Names and photos of headstones that are still in the cemetery are on FindAGrave. If you see a problem or duplicate, please let me know (nicely!). If there is no photo attached to a record in Willow Grove, the headstone is likely no longer visible or has been damaged.
Also, New Brunswick Public Library received an enormous donation of old articles from the Home News of East Brunswick. As obituaries were found, they were added to FindAGrave memorial pages. If you would like ownership or would like the memorial deleted, please let me know (nicely and briefly) via email with the memorial number. I do not have any other information about these people other than their obits.
Photos of headstones at Christ Church Cemetery (New Brunswick) were added at their request and a link to their page is on each photo.
