Thomas Henry, Tullaboy, had a great interest in ponies and was often called upon to advise or help when a neighbour had a sick or ailing animal. Veterinary surgeons were few and far between in those days
In 1893 the Congested District Board offered a chestnut Welsh Cob stallion to George Lyons of Bunnakill but this animal was instead located with Thomas Henry and named Prince Llewelyn. Thomas Henry would have had a number of good Connemara mares. Dynamite and Powder were two of the offspring of these and both were sired by Prince Llewellyn .
Dynamite was chestnut in colour and was a famous trotting pony. He was the sire of the famous Cannon Ball and won many prizes for style and action before being sold to a wealthy American for £100 travelling from Cork aboard the SS Umbria on 16th October 1904 (the year in which Cannon Ball was born).
