I believe we are cousins. My mother, Miriam Slattery, was Derry's first cousin, I think. Which makes us second cousins once removed. I met him a few times at Goodwood races, he was a sweet man. I'll see if my sister knows anything more about him. I happened to find your request when I was searching for some information on him - my partner is in the racing world. I think I remember him saying that his daughter was a nurse working in Singapore, but I remember very little else about him, he was always in a rush to the next race when we caught up with him.
