Denis Leary (O'Leary) born 1894, Cork
I know it is quite unlikely for anyone to have any knowledge of Denis (O')Leary but since there is so many Denis' in cork I have hit a wall to who his parents or brothers and sisters were. He had 7 brothers and a sister and I believe his mother died when they were young so his sister went and moved with an uncle. He joined the army during WWI then fought for Irish independence in 1920's. After he married Clare Perry then later on moved to England.
His son (my grandfather) died a year before I was born so I haven't had a chance to ask him about his side of the family and my grandma cannot remember any names or dates.
If you can offer me any advice about what to do next it will be very helpful. Thank you.
