Anyone else know a high school senior that is married?

My niece recently married her fiancé. They have been together for 3yrs and have one child. He is a couple years older than she is. She will be 18 in September. He was in the Air Guard and working construction. He has decided to enter the Active Duty Air Force to provide insurance for their family and will be off training for a new job then establishing them when he obtains his base assignment. She begins her senior year Sept 1st. They've had their own apartment renting from family for a little over a year now.
