Helen,
I recall J. Coogan Snr's WW1 medals being sold on ebay about 3 or 4 years ago.
He served in an Irish Regiment in WW1, possibly R. Dublin Fusiliers and transferred to the Manchesters after WW1, serving in the 1st Bn. I think he may have won the Military Medal.
He was an accomplished Boxer, Pole Jumper, Long Jumper, Footballer, Tug-f-war and Lewis Gunner winning several prizes.
His son J. Coogan was also a good boxer.
Hope that assists.
