I am looking for information concerning the ancestry of John Sarsfield Casey, he was born in Mitchelstown, Co.Cork in 1846 and is buried in Mitchelstown cemetery he died in 1896. His parents names were Jeremiah Casey and Honoria Lewis. It is believed in my family that he is connected to us if this is so I believe he may have been the nephew of my Great Great Great Grandfather John Casey and his brother Fr Daniel Casey both born in Kilbehenny, Co.Limerick around 1820. I have no proof of this - I am looking to confirm that Jeremiah Casey was John and Daniel's brother. Please find a brief bio below on John Sarsfield Casey - any help on this would be appreciated.
He was born in Mitchelstown on the 2th March, 1846, and in his early years he worked in the public house of J.J. Geary’s at 27 North Main Street, Cork, where he was arrested and taken to Sunday’s Well Gaol on the 28th September, 1865. In December he was removed to the County Gaol. He was tried and convicted on the 29th December and a week later he was taken to Mountjoy Gaol. After a ten days sojourn, he was moved to Pentonville Prison, then to Portland Prison, and on the 24th December,1866, to the new Portland Prison. Finally he was put on bard a ship on the 8th October, 1867, which sailed on the 12th October and eventually arrived in Freemantle Australia on January 9th, 1868. He was sentenced to five years for treason-felony, and was one of the 62 Fenians transported to Western Australia. He was granted a free pardon on the 15th may, 1869, and he sailed for Ireland from Melbourne on the 26th October, arriving at Dublin on the 18th February, 1870.
Immediately after his return to Ireland, Casey wrote a series of articles on conditions in Australia, and he also became noted for his work on behalf of the tenants of the Galtee countryside. In his youth he came under notice of the police following letters which he wrote under the nom-de-plume “The Galtee Boy” in the Fenian Newspaper. Later he became a coroner for Co. Limerick which position he held at the time of his death, on the 23rd April, 1896. He is buried in Mitchelstown Cemetery
