My uncle, Patrick Mason was KIA at Memetz Wood on the Somme on the 14th. July 1916. I have all reasonable info. from CWGC, regt. no. etc and I know that his name is on the Thiepval memorial. He served with the Royal Irish Regiment. I want to find out if he was a regular soldier, where and when he enlisted etc. My uncle was the first born, (illegitimate), son of my Granny, Ellen Maher (nee Mason), from Clogheen, Co. Tipperary. His age at his death was given as 25, dating his birth to circa. 1891. I cannot find any details of his birth. How do I check now with the Royal Irish Regiment as to Patrick's service record. Any help from my Rootschat pals?
