The horse in the picture is probably 'The Tetrarch' , nicknamed The Spotted Wonder, winner of a number of classics and buried in Ballylynch . Tom Murphy looked after him. Tom trained greyhounds also and had a taxi in Waterford in the late 50's, before moving to Birmingham. My sister, Joan, was in regular contact with Jim Murphy for many years before he died, and I also emailed him a few times.
Nell O'Neill married Fred Gaskell, but there was not much contact between the families. It would be good to meet after all these years. Not sure if Tony (Gargoyle) followed up on his earlier contacts with Johnny Kelly c.07. I only became aware of the posting recently.
