Names for a boy!!

My husband and I have a very short list: Shiloh and Cyrus. So I figure we’ll take both names to the hospital and decide then. Our issue is middle names. I like short (one syllable), but since the names aren’t that masculine, I would like a stronger sounding middle name just incase baby boy decides he’d rather go by that in the future. We have no one we want to honor and it was hard enough finding any first names we even liked enough to consider. Help!!
