Update........James Grehan was born approx 1832, in the village of Ballynoonagh, Clonbur, Galway. His parents were Michael Grehan and Bridget ? They were tennant farmers, farming approx 12 and a half acres on the shores of Lough Mask. Other children besides James, were Thomas, Isabella and possibly Ann. Isabella took over the farm after the death of her parents, and eventually married Thomas Manion. Thomas and Isabella, had at least three children. Michael Manion born 27 June 1872, Bridget Manion born 13 July 1874 and Mary Manion born 24 March 1876, all in Clonbur, Galway.Thomas Grehan; James's brother, also joined the Royal Irish Constabulary but where James served for 30 years, Thomas only served for one year. Thomas married Honor Walsh and they had at least two children. James born 16 November 1875 in County Mayo and Honor born 19 October 1880, in Clonbur, Galway.
James started his Police service in 1853 in Roscommon. He married twice. Firstly, Mary Glennon and secondly, Matilda McNicol. He married Mary Glennon in Cam and Kiltoom, Roscommon on the 1 June 1861. Their children were:-
Michael Patrick Grehan born 9 March 1864, in Newport, County Mayo. Died 12 June 1865, aged 1 in Ballynoonagh, Clonbur, Galway.
Edward Joseph Grehan born 14 March 1865, Newport, County Mayo.
Michael Patrick Grehan born 18 August 1867, County Mayo.
Bridget Grehan born 25 November 1868, County Mayo.
Mary Grehan born 23 July 1871, County Mayo.
James Grehan born 27 February 1874, Achill Island, County Mayo.
John Grehan born 31 May 1875, County Mayo.
Mary Glennon appears to have died sometime between 1875-1877.
James then married Matilda McNicol 12 September 1877, in Kilmain, Ballinrobe, County Mayo. They had at least three children:-
Teresa Grehan born 9 July 1878, Newport, Coutny Mayo.
Matilda Grehan born 9 November 1879, Newport, County Mayo.
William Thomas Grehan born 11 May 1881, Drumlong, Newport, Couty Mayo.
In 1883, James was stationed in Clairemorris and his wife and children were with him. He was then sent away from his family, back to Newport. It was an agreement within the R.I.C. that married men with young families, should not be separated from them. However, James was sent away from his family. He wrote a letter to his superiors, expressing his desire to be able to be stationed close to his family. For some unknown reason, probably punishment for making the complaint. James was sent even further from his family, to a Protection Hut at Carros, County Mayo.There, suffering from depression, James committed suicide on the 14 April 1883.
What became of Matilda and all the children, I'm yet to find out. All I know is that the youngest child, William, shows up on the 1891 census for Glasgow, Scotland. He is aged nine and living with his mothers brother, James McNicol and his family. William became a barber. He married twice. Firstly Catherine Sherry, and after her death, he married her sister Helen Sherry.
The only other information we have for the siblings of William, is that his brother James, who was born in 1874 in Achill and is mentioned above, could have been murdered in America by a Hobo/Tramp whilst on his way home from work with his wages. It is rumoured that some Grehans went to America and that they may now be called Graham. Also one may have gone on to become a priest and that a more recent one, is a Nuclear Physicist.
