Thomas Kirkwood and Jane Gray

I am visiting Belfast in October 2022 to do research on my Kirkwood/Gray family.  I know my 2x great grandparents were Thomas Kirkwood and Jane Gray.  I found a couple in Inch Parish married in the COI Inch April 1821 who had a son Robert baptized 1822 and a daughter Jane 1824.  The family left for Antrim sometime after 1828. My direct ancestor Sarah Kirkwood b about 1836 was married to a David McKee in Belfast, at Townsend Street Presbyterian in Oct 1856.  The couple emigrated to New York City in 1860.
 

Does anyone have connections to Inch Parish? I am thinking about trying to visit while I am in Belfast
