Charlie and Renee are Aiden and Evan’s grandparents. They are fun, caring grandparents and love seeing their grandchildren when possible.
Carlisle and Esme are Samantha’s grandparents. Not mentioned in detail.
Emmett Sr. was Emmett’s grandfather. Emmett and his grandfather had more of a father/son relationship because Emmett Sr. had to raise Emmett after his parents both died. They were all the other had as far as family goes and were very close.
