Greetings from Bailieborough. I am aware of two Davidson families who lived in these parts both were Presbyterian. One family attended Glasleck Presbyterian Church (Shercock) the other family attended Corraneary Presbyterian Church. In Glasleck church's financial report dated 1865 there is a Robert Davidson listed and again in 1897. The graveyard map records Robert Davidson, Dromod but on the ground there is no headstone or grave markings. This family no longer exists in the area. The Davidson's who attended Corraneary church have decendents still living in the area and if you send me an email (address on attached website) I can put you in touch.
