Names that go with Luther?

[-dharmamama-.livejournal.com]

I'd like to include my great-grandfather's name somehow, if this baby is a boy. What are some good first names that go with Luther as a middle name? Any ideas for middle names if you think Luther is okay as a first name? We were thinking about calling him Luke as a nickname if his first name is Luther. It's such a traditional name - that's why I'm at a loss.
