Here's the obituary I found for you a while ago-
Belfast Newsletter, 10 Feb.1866: PALMER- February 9, at 4, Montgomery Street, Belfast, Catherine, relict of the late Skeffington Palmer, Killead. Her remains will be removed from her late residence for interment in Antrim Church-yard on Monday morning, the 12th instant, at ten o'clock. Friends will please accept this intimation.
Another-
Northern Whig, 8 Jan.1900: PALMER—January 5. at her residence, Mount Cottage. Dungormell, Margaret Moore, beloved wife of John Palmer. Her remains will removed for interment in Antrim Church Burying-ground ...
Husband John's death notices the following year also mention the family burial ground, Antrim.
Can't see burial instructions in Will but to be honest the writing in the Will Book is so difficult to read I could have missed it.
Probate of the Will of John Palmer late of Dungonnell Killead County Antrim Farmer who died 27 March 1901 granted at Belfast to John S. Palmer and Walter Palmer Farmers.
