Great Great Grandma Nylund was the great great grandmother of Charlie Nylund, Rose's late husband.
In the episode The Stan That Came to Dinner, Stanley Zbornak, who was staying at the girls' home after a heart surgery to recover, accidentally broke Great-Great Grandma Nylund's ceremonial wedding plate. Rose was angry, of course, along with Blanche whose date Stan accidentally ticked off.
