Hi Gingerleo and welcome to the forum.
As Magic Star says, Leo is very similar in looks to my Jimmy ( who is, in my biased opinion the most handsome Cocker that ever graced the planet - others would no doubt disagree though
) - I doubt they are very close relatives though, unless you travelled down to the SE of England to get him.
Nice pics - he's very handsome, reds/golds are my favourites so I always like to see photos of them.
