What do you presume of these name?

Okay, my husband (John-William) and I just found out that we are having quadruplets. 2 boys and 2 girls. Yay! The only problem is that we can't find name that we like that go together. We like the name Johanna and Peter but we can't think of middle names and names for our other daughter and son. We really close to old-fashioned names (like Peter and Johanna lol). Oh, and our last entitle is Van Der Schans (i know a mouth ful). Anyways, we would really like any suggestions. Thanks.
