Your grandfather , I knew him as Jake Kilrain, was a very good friend of my father ,John Donoghue( Who played for Celtic with Mc Grory, Thompson etc from 1926 to around 1930) They both worked at the Union Club in Renfield Street around in the 1950,s. I met him on quite a few occasions Always very friendly to me although he had quite a fearsome reputation The last time I saw him was in late 1965 just before I emmigrated to Canada lHe was working at Hamilton Race track. always remember he gave me a tip for a horse FLIGHT MASTER( Lost in a photo finish0. My father spoke about him quite often his fight with Ernie Roderick at Shawfield etc. I once saw a photo of him and his wife sitting with my father and my mother at a Union Club social event... wish I had it now. Just thought I would add this little bit of Info. John D.
