Civil engineer. David Aher, who is described on his gravestone as being 'of Castlecomer in the county of Kilkenny', was born in 1780 and began his studies as a civil engineer at the age of fifteen. In 1803 he surveyed and superintended several works for Grand Canal Company and later directed collieries in Cos. Kilkenny and Laois, when he was responsible for various innovations and improvements in mining and boring machinery. From 1810-12 he reported to the government commissioners who were inquiring into uses for Irish bogs. He laid out nearly all the new lines of road through Co. Kilkenny and the Great Leinster & Munster Railway from Dublin to Cork. In 1840 he 'met with some disappointments and losses, which weighed heavily on his mind, and were the principal cause of the illness which terminated his life'. He died on 5 May 1842, 'respected for his high professional attainments and strict integrity of character, and regretted by all who knew him'.(1) He was buried in Mount Jerome cemetery. He had married Susan Wilkinson at Corballis, Co. Meath, in 1807; four of their children survived him.(2) His sister Mary married HILL CLEMENTS , who collaborated with him on the survey and mapping of Co. Kilkenny and other projects.(3)
