John O’Callaghan was a mason, based in Fermoy, Co.Cork- possibly in Newmarket St. Rumour has it that he fought in the Crimean War. He had at least one son, Peter O’Callaghan, who also served in the British army in Egypt/Sudan and Bermuda. I would be very grateful indeed if anyone knows anything else about this John O’Callaghan and whether or not he had any other children. I know that he was still alive in 1888, as he is mentioned on Peter's wedding certificate, but after that I can find no record of him as yet. He was more than likely buried in Kilcrumper Cemetary, and there is a record of a J O'Callaghan, mason, being buried there, but no date is given.e
Thanks,
