#4. Barry John & Scott Quinnell (Uncle and nephew)
Quinnell went down in history as one of the greats, not only of Welsh rugby, but the world game. His father Derek was a star forward for Wales and the Lions, his uncle was a certain Barry John and his godfather was No 8 great Mervyn Davies. Despite retiring aged 27, John would be regarded as one of the finest Wales and lions fly-halves of all-time.
