What middle name combo is best?

My husbands only request when it comes to naming is that all our kids have two middle names (his whole family does, and I have 2 last names, so we'd all match with 4 names total). We've got a first and one middle name, (Isaac Alexander) but are struggling with the second middle name. His names are are a bit odd, so we're alright with unusual names. We're also both giant history buffs and nerds, so a lot of our choices are historical. Our last name is Neal.
