All my barn cats are black as well. I've named a few - Hunter (I think this one is a mom with a litter next door, she hunts every morning in our front field), Bruiser (big ol' burly thug, but friendly as can be, he often lays right where your next step was going to be and rolls over for a belly scratch), Boots (long hair with white feet), and Boots-2 (short hair with white feet). A couple others come and go, not as regularly. I'm not sure if these cats are feral or just opportunists, some are quite friendly, others skittish. I occasionally set out food for them when it's cold, although they all appear fit. Whenever we get a house cat, I usually go with a gray tabby. Our last one took 'the long walk' after 18 years. If/when the mice infiltrate the house, we'll get a pair of kittens.
