Baby boy names

We have the name Isaac picked out but we aren’t sure on a middle name. My husband likes Allan but I lived on a road named Allan so I don’t want that name. Then he also likes Scott which is my dads name. I don’t mind Scott but we both have talked about William also my dads middle name. Other wise I’m stuck on names. I don’t want bible names (nothing against the Bible just a preference I have). I like unique names, my daughter has one and I’m not sure if our son should have one too. My husband doesn’t like names that are towns or city’s, and I don’t have a preference.
