German baby names

Kristi • I'm a stay at home mom to a little boy who's 2 years old. I'm currently pregnant with my second who is due 10/17/16.
I'm 5 1/2 weeks pregnant with my second. I'd like to start thinking about a few baby names to propose to my husband because he never agrees with any. We are both primarily German decent and I'd like a name to go along with it. Our son is Albert IV. I'd like something a little different, less popular, but doesn't sound too old fashioned. Looking for both boy and girl names.
