They look like Southdowns (NOT Babydoll Southdowns) Probably not anything fancy (ie not show quality), but they will be great for what you want them for.
They won't have the best wool if you are thinking about learning to spin or trying to sell it. It's a medium staple fleece and while some Southdowns have decent fleeces, the breed has not be bred to select for nicer wool since they are a meat breed.
I would HIGHLY recommend getting the lamb's tail docked as soon as possible. A long tail in a wool breed is a recipe for fly strike. Believe me. You do NOT want to experience that. You don't have to dock really short, maybe leave the tail 3 or 4 inches long.
The ewe looks Southdown-y, probably a cross with a whitefaced ewe. The lamb I want to say has a Hamp or Oxford daddy, but usually with those types of lambs, they have speckled faces not solid faces like this one.
Their faces look too open for me to say pure Southdown, which is why I said Southdown x. My neighbor had a Babydoll x Montadale ewe that looked like the ewe in question, I named her Wrinkles... but their faces are pretty similar in terms of openness.
Possibly...there is variation in amount of face wool within the breed so I wouldn't base anything on that. The thing that makes me think possible cross is their ears. Their ears are a bit too "perky". The tips of the ears point up a little instead of being closer to horizontal.
