Anyone up for a little challenge?

We need help finding a very specific baby name. This is baby #4 so coming up with new names is hard!

Our children are named

Callahan (boy)

Bodhi (boy)

Rosemary (girl)

Here’s our weird request: normally people try to avoid repeating letters, but we actually want to repeat one. So we’re looking for names that start with a C, B, or R. We don’t know the gender so ideas for both please!
