Suggestions for Brevlin's sibling

We are finding out the gender of baby #2 in a week. While we are not in a huge rush to find his/her name just yet, we would like to have sooner rather than later. Our first daughter's name is Brevlin Cassidy. Brevlin is my mom's maiden name. At the beginning of this pregnancy, we weren't going to find out the sex of this baby and just name it Carter, regardless of its gender (Carter is my mil's maiden name), but it just doesn't feel right. I would appreciate names for a boy and a girl that could go with Brevlin. Thanks in advance!
