comment1. are you the H......R...... above?
2. the estimated marriage date for a Alexander Gibson m a Janet Moore is 1794+24 = 1818 location unknown yet its on a newtownards board.
Church records for Newtownards the surviving church records are listed
http://www.rosdavies.com/CHURCHES/K_W.htm#Newtownards3. You interchange Stewart to Stuart b 1812[-1814] , i understand that vision of records of those days
4. the website compiler Derek Beattie died suddenly in 2016, his 10 special friends have resurrected his website however his sources for each entry aren’t obvious to me yet.
I stop here for encouragement or advice
