SANTA CLAUS, Ind. – At Will and Ashley’s wedding this October, the bride and groom weren't the only ones in the spotlight.

Ashley’s sister, Hannah, shared in moments as well.

Hannah, 15, has Down syndrome and diabetes and will always need to be in her older sister Ashley's care. When Ashley, 23, and her boyfriend of seven years, Will, started talking about getting married, she joked that he never thought he’d have to marry two girls at once.

Little did she know, that’s exactly what he planned to do.

During an annual family photoshoot, Will got down on one knee and asked Hannah to be his Best Friend Forever.

“She was so excited, and I looked at Will and said, ‘I’m probably next, right?’” said Ashley.

At the wedding, Will and Hannah shared best friend vows. Among Hannah’s vows were to share secrets, go fishing and take care of one another for life. Hannah and Will also had a first dance to “Best Friend” by Harry Nilsson during the reception.

“Weddings aren’t all about love and lust and everything. It’s about bringing two families together. I’m bringing Hannah as my family into this.”

Hannah picked out her own white dress and will have the title “Best Sister” in the ceremony. Ashley doesn’t mind sharing her day with her younger sister.

“It doesn’t even cross my mind to think that I’d want it by myself,” says Ashley.
