Help with baby names!

We are finding out the gender of our baby at birth so we need to come up with a boy and girl name. Please help me.. both of our other kids have very timeless old simple names. So anything that’s the same vibe nothing whimsical, or earthy, or “different”😅 I like simple names that have been around for ages but also maybe not so common anymore.

The 2 names I am kinda thinking of is either Katerina for girl and Phillip for a boy. But honestly not 100% about either which sucks because my other 2 I was 100% about them before I was even pregnant with them😭
