Nancy,
As you probably already know, Kirkpatrick/Kilpatrick are interchangeable in Ireland and so you will see the spelling switch from one to the other.
You don?t say what denomination your ancestors were. Looking at the available church records for Loughguile, I see that the Church of Ireland has baptism records for 1802 ? 1814 and 1876 onwards (intervening years lost in the 1922 fire); Presbyterian 1862 onwards and RC 1845 onwards. Kilraghts 1 st & 2nd Presbyterian churches are also in the area. Kilraghts 1st has baptisms from 1831, the 2nd from 1855. So Kilraghts 1st is the only one covering the years you are interested in, and even then only just. (There's a copy of those baptism records in PRONI).
Looking at Griffiths Valuation for Loughguile in 1861, there are no Kirkpatrick households. There are about 10 Kilpatrick households. They were in Drumdallagh, Coolkeeran, Turnagrove, Ballynagashel, Ballytaggart, Culbane & Ballyportery South.
By 1901, there were Kirkpatricks in Turnagrove (5 households):

All Presbyterian. They were the only Kil/Kirpatricks in any of the townlands listed in Griffiths.
Here?s a link to someone researching one of those families. (You might be able to compare data and DNA with them. Some of the names are similar to yours. Might be a connection):

The modern Drones Rd BT44 runs through Turnagrove. I searched the modern phone book and there are non Kil/Kirkpatricks listed for Drones Rd but there are 4 in the BT44 area. You could try getting in touch with them to see if they know anything of their ancestry. 50% of the population are ex-directory these days, so that?s probably not a comprehensive list. Local enquiries may find you others
There?s 7 Kirkpatrick probate files for the Turnagrove family in PRONI. Here?s one example (the will itself is on-line). You can search the site for the other townlands too).
