Thank you all for your replies and I apologise for the delay in replying. I will try and explain why I wanted to get the records of St. Columba. I have been doing my husband's family tree for a number of years and have decided that I can get no further but just thought I would check on a couple of things that had puzzled me. His gt.gt. Uncle was a John Browne who married a Catherine Kirby in Islandeady on 8th March 1868 and they had four children : Thomas 1870, William 1872, Honor 1874 and Mary Anne 1876, wife Catherine died in 1877 and John remarried in 1878 to another Catherine, this time Catherine O'Malley this couple had at least three children born in Ireland but they then moved to Lancs. circa 1881/2. I was always puzzled by the fact that in the 1891census, their first census in England there was no mention of the first four children and I assumed that they must have died as I had found mention of the death of Mary Anne in 1883, why else would you leave young children behind? So whilst doing a last, as I thought, check on these children I discovered a reference to Petty Session Court Registers in this register there is a mention of two girls, one Honor Browne aged 5 of Cogaula and a Mary Anne Browne aged 3 also of Coguala under the name of witnesses was Mary Kirby for the complainant (grandmother?) the two girls were accused of begging in Westport they were described as orphans having lost one parent and living with their father and had no visible means of subsistence. On the 25th of SEptember 1879 they were sent to St. Columba Industrial School and Honor was said to be detained until 25th Sept. 1890 and Mary Anne until the 25th Sept. 1892. It a way it does not make sense John had remarried by 1879 so did wife no.2 not want the children from his first wife?
Obviously with the death of Mary Anne in 1883 I assumed, probably wrongly that she died at ST. Columba so I thought that if I could find some records of entries or releases or deaths relating to these girls I could confirm whether or not they were part of my husband's tree. I could find no positive mention anywhere of Thomas or William.
So there you have it the reason why I was looking for any records. I must admit I thought it a bit harsh that such young childen were treated in this way.
thanks for reading this, Joan
