PRONI guide to church records sadly doesn’t list Cemeteries

However another website
http://www.rootsweb.ancestry.com/~irlantbp/john1.htm Gravestone Inscriptions at the old burying ground beside Billy Parish Church in North Antrim
These pages are experimental and part of a project by John A I McCurdy, Shane McCurdy and Norman Parkes to catalogue the cemetery. For convenience of presentation and updating, the burying ground to the south of the Parish Church has been divided into 9 sectors. There is a detailed plan (due to John McCurdy) showing the locations of the stones at the bottom of each sector of inscriptions and an approximate plan of the sectors on this page. Inscriptions checked and edited by Ian Page, 2004.
There are some items of background material from John McCurdy:
