I need a first name to go with a middle name of William?

My husband and I can't decide on a first name if we have a little boy. The baby wouldn't cooperate for our sonogram. We already picked Ava Raylene if it's a girl. We want to use William as a middle name because that's my husband's and my grandfather's middle name. Our last name is Jones. We don't want anything too unique or too popular. Any help would be appreciated. Thanks!!
