There is a Robert Jackson listed as a WITNESS at a wedding in Tydavnet Church.  He lived at Telaydan which is in Donagh Parish.  Because the Jackson name is largely Presbyterian I checked & found several Robert Jacksons in the surrounding Churches.  Your dates of birth (1822/3) seem to fit in but I'm not sure.  The Church Records of all of these Churches have now been copied to CD & are readily available.  You may wish to contact me directly at (*) & I will try to assist.  I am currently copying the Parish of Ematris to CD but the following Churches are already copied - Tydavnet, Kilmore, Scotstown Pres, Tyholland, Glennan Pres, Ballyalbany Pres, First Monaghan Pres, Clontibret, Legnacreeve / Braddox Pres, Derryvally Pres (marriages only), Corlea Pres (marriages only), Donagh, Monaghan (St. Patrick's)(births only) & Ematris (being copied now)
