Thanks for your reply brian.
Since I last posted I have found who I believe to be my G Grandfather on the Ancestry site ,where they list police officers in Ireland. I had viewed the 1911 census at my local LDS church and on it was his age and I could link it to the age of a Charles on ancestsry. If indeed it is him he joined in Galway and seemed to go everywhere. He married a Jane Adam from Londonderry, married in Enniskillen, had children in Cork, Kerry, Galway and Clare. He certainly travelled! He ended up in Cornamona retired and having a new career as a Postmaster and farmer. Wow! I am at present awaiting the film from the LDS relevant to my grandfathers police career, if indeed it is him.
Will update as and when.
