David,
According to the UHF site there are 5 cemeteries in Templepatrick parish: Craigarogan; Templepatrick Old; Templepatrick Church of Ireland; Mallusk & Umgall. The site has the map co-ordinates for each graveyard:

Finding where someone is buried in Ireland can be tricky. Not all churches had a graveyard, especially Presbyterians. In addition, folk weren’t always buried in the graveyard associated with the church they attended. They often had family plots in unexpected places (perhaps where ancestors used to live) and so it can be tricky finding them. Presbyterians in Ireland don’t use the parish system and can often attend a church some distance form where they lived and they often used a different graveyard. It's common for Presbyterians to be buried in Church of Ireland graveyards. Also Presbyterians don't normally keep burial records, so that doesn’t help either. The area around Templepatrick is full of churches and graveyards, but I would start by trying the 5 I have mentioned.
