Phill05 does have a point; it does look like you might have two species in the photos. My first reaction was cherry. The one at the back has a bit shinier bark, so could be plum, but could also still be cherry. Doesn't look like apple or pear to me; the rings/grain ae not fine enough for pear (or apple, I think).
The guy who said it wasn't cherry.... on what basis was this? Fruit, leaves? Wishful thinking?
Before I knew any better I was sold a load of cherry by a guy claiming it was laburnum. He claimed it had yellow flowers! It had what looked like a brownish heartwood which turned out to be discolouration due to rot. More detailed research convinced me that the chance of it being laburnum was about as likely the first circle of hell freezing over!
