Both gorgeous! The second one looks like a Marley to me, or maybe a Misty. The first one's markings remind me of a Bernese Mountain dog, so Bernice or Sugar are coming to mind (damn Eastenders for that).
I like a theme with my names, I have Sangu, Meeru, Rufiyaa (3xcats) and India (all maldives related) So I would go for Snaffle and Pelham or Barley and Maize! But as they are yard cats and you may need to call them without sounding like too much of a wally, I would suggest Jute and Witney
