    Adapted from memories from the family:
    Nannette was a fun-loving, adventurous, independent, determined, generous, and passionate person. She was the first female head cheerleader of the Ohio State University team, where she met and married her college sweetheart and football star, Joe Campanella. Joe later became a local celebrity as a professional football player for the Baltimore Colts from 1953-1957.

    Nannette and Joe had seven children together. They started a restaurant chain called Gino's which had more than 350 restaurants along the East Coast. Later, Joe founded Rustler Steak House. They sold both companies to the Marriott Corporation. When Nanette was pregnant with her seventh child, Joe died suddenly and tragically at the age of 36.

    About nine years later in 1976, she met and fell in love with Jesuit missionary priest, Dr. Lawrence B. Dietrich, Jr. While on a mission in India, Lawrence proposed to Nannette with this Marcus & Co. Kashmir sapphire and diamond ring. The ring marked for them the beginning of a new life filled with discovery, hope, and love. They raised seven children, 15 grandchildren, and four great grandchildren together. They remained happily married until they both passed away in 2019.
