Help with baby boy names please

My husband and I want to go to the hospital with 2-4 boy names; then know which one fits our some the best once we see him. The problem is; we only have one name idea so far and I’m due in 3 weeks. I’m in the education field, so there’s soooo many names (of students I’ve had) that are out. We don’t want common names; instead we prefer unique and biblical names with proper spelling in them. His middle name is Alan, a family middle name. Any ideas you can give me?
