Carlisle is very man-servant to me. "An intellectual says a simple thing in a hard way. An artist says a hard thing in a simple way." -Charles Bukowski
Moses, Pompey, and Amos have the vibe of American slave names. So does Lydia, to an extent. Carlisle is a British servant name. Didn't the British used to call their male and sometimes their female servants by their surnames? That's why.
