What is recorded here

St. Patrick's CoI Church in Upper Badoney bears a blue plaque marking the birthplace of James MacCullagh, the mathematician and physicist who lived from 1809 to 1847. The Ulster History Circle recorded his name on the building, preserving his identity against the fading memory of time. A young man from that parish changed how people understand light and motion, yet his origin remains tucked inside an ordinary church wall.
