An East Tennessee grandfather got a letter on Christmas Day that brought him to tears.

Marvin Wilson, 84, got a letter from his grandson Aaron telling him how much he has meant to him throughout his life. His daughter was filming as he read the letter out loud, holding back tears.

Wilson keeps reading and learns his great grandson, due in April, will be named after him.

His name will be Wilson Grant Owen.

His daughter says Grant is the name of the mother's grandfather so their newborn will be named after both grandfathers.
