Judge Thomas Trempe performed the ceremony on Friday in front of a small gathering of family and friends.
Greene, 23, said she and Royce, 19, knew each other in school, but officially met through friends and began dating 14 months ago. They now share a home together in Springfield.
Greene said she cried when she found out about the Supreme Court’s decision legalizing gay marriage last month. Her new wife helped her wipe a few tears from her face during the ceremony Friday as well before declaring, “We did it!”
The couple plans to hold a larger, country-themed wedding in the future.
