The moment that Hannah was born, she was inseparable from her older sister Ashley. Ashley knew that she'd always stand by her sister, who was born with Down Syndrome, for the rest of their lives. They're a package deal, and Ashley's fiancé, Will Seaton, understood that perfectly.
When he asked for Ashley's hand in marriage, he actually knelt and proposed to Hannah too! Now, Ashley and Will are walking down the aisle with Hannah right beside them. They made it a point to ensure that Hannah felt included, and Will and Hannah even exchanged their own adorable "best friend" vows at the wedding. It really is a true testament to love.
