If any one could please help, I would be immensely grateful. My great grandfather and three of his sons saw service in both the British and Irish Armies, the resemblance to one another at a young age is uncanny. I am trying to date this photograph and hoping that the uniform might help in order for me to identify the people in it.
My great grandfather P. WILLIS saw service in the Connaught Rangers 1914-1920 and then on to the Irish National Army; his sons first joined the Irish Army and then on to give service to the British Army during WW2.
Thank you in advance
