Iniscarra Cemetery, just a few miles from where I work, holds the remains of one "Mary William, daughter of John Stewart of Belfast. Wife of the very reverend Theophilius Blakely, Dean of Down". She’s also the mother of Captain Theophilus Alexander Blakely, a prolific designer of rifled cannon and the inscription on the side of his mother’s tomb bears witness to that:
Mother of Captain Blakely Royal Artillery. Original inventor of improvements in cannon and the greatest artillerist of the age.
A quick search proved useful and it was sobering to find a connection between my locality and the American Civil War!
