I usually just roll with whatever names the players come up with. For instance, in my current campaign, one of my players came up with a cleric of Kord named "Cal Trop." So, when an adventure took place in a small village where sheep and goats were raised, I decided that Cal's brother, a goatherd named "Trip Trop," lived there, and he became my plot hook for that session. I've also decided that they have a sister, "Yvonne Trop," a singing bard who looks suspiciously like Julie Andrews.
They give me silly, I give them silly right back.
