I find it hard to tell what information you want to know about the interesting and ever changing Conlig, eg Google search, Ros Davies website has been mentioned to you, it contains photos [and a contact] and newspaper cutting references, church records etc that exist. Then how about the Public Record Office of Northern Ireland [PRONI] ie
www.proni.gov.uk/ . their databases include eg freeholders, covenanters, etc.
The leaseholders over the last 200 +years probably include the surnames Allan-Boden-Bowden-Boyd-Duff-Dunn-Makey-McAlister-McBurney-McClement-McCloy-McCoy-McCutcheon-Miller-Neilson-Pirrie ?-Smiley-Thompson-Walshman-Watterson-White. Some of these leaseholder documents may include maps. I say probably because there may be another Conlig in Co Tyrone and I havent the time to work out which is which.
However when the Ulster Covenant in 1912 is being signed or its declaration is being signed the surnames don’t include any of these names, but do include probably Adorian-Brown-Burns-Cammock-Carlisle-Conway-Cooke-Cowan-Dalzell-Finlay-Gambill-Gamble-Gordon-Hamilton-Hanna-Henderson-Johnston-Leodley-Lightbody-Lowry-Lynn-Major-McCooleagh-McCreedy-McGimpsey-McMeekin-Montgomery-Moore-Mulholland-Rea-Russell-Scott-Sloan-Smith-Stone-Syria-Welsh-Williamson. Then you examine the gender of the signatories and nearly all are female. This is an extraordinary result compared to many localities where the balance is normally a large male majority. So what was the reason? Why are none of the surnames among the leaseholders. What does it mean?. While discussing PRONI, they have many large collections of Montgomery papers listed in the private collections, presumably some include the Conlig connection.
The six inch OS maps dated 1830s and 1860s exist at OSNI, and at the LinenHall Library, Belfast. Comparing the two maps is easy and interesting, the townland area is about A4 size.
The archaelogy will be covered in books and journals. Flora and Fauna may well recorded.
I would be interested to know if any of the mineworkers died of lead poisoning or sterility from same. Was there any radioactive material found at the mine. You have references for some books covering this. Socially the area seems to have been used for motor or motorbike events. Did the TT races go thro the area
In WW2 the german bombers would have been coming overhead on a flight path to Belfast, are there any memories recorded.
I wondered if some local history group has ever existed? Have you tried the local Library hdgs at Ballynahinch?
Finally I have part of a simple family tree relating to a branch of Whitlas in the Conlig area, who migrated to Canada.
Good luck on your search, Jim
