I take the first letter of the name they came with and rename them for someone I know or a common name I like... for example City could become Cyndi or Chelsea, and Mahalo is now Michael. Occasionally I'll leave their names alone for a generation just to make it easier at a glance to delineate ages, but most generally I change them.
