Kelsey Poll was working as a bank teller when Tyler West walked in. Sparks flew and they started dating and then he asked her to marry him. As the couple planned their wedding, they looked through old family photo albums and came across Poll's baby book. There was a photo of Tyler's mom, Mary Ann West, taking Poll's footprints. Unbeknownst to her, the Utah nurse helped deliver her daughter-in-law 22 years ago.
