On Rylee’s 18th birthday he made that choice, to offer his service to the country.  Family members say becoming a Marine was a life-long goal for him.  He joined the Marines.  He graduated Marine Corps Boot Camp at Camp Pendleton, on 6-DEC 2019.  While he was at boot camp he met “Gigi” the woman who would become his wife.  His sister said, “He dreamed of one day becoming an American history teacher and a wrestling coach, passing down the same passions he picked up as a kid in Jackson.”

Shortly after his Marine Corps graduation Rylee and Gigi married on Valentine’s Day 2021 and were expecting a baby 22-SEP 2021. Rylee was excited to become a father.  His family expected that he would be home just in time to meet his new baby.  The newlyweds wanted the baby’s gender to be a surprise.
