Rose Blake (Novel Series)

Rose Blake, her maiden name being Rose Garcia, is the mother of Philip and Brian Blake, the wife of Ed Blake, and  the grandmother to Penny Blake. Not much is known about her, but she is mentioned in The Walking Dead: Rise of the Governor.

Pre-Apocalypse
Rose was of Mexican-American ethnicity, her husband being Scot-Irish. Before she was married to Ed, her maiden name was Garcia. The story also implies that her sons, Philip and Brian, call her, "Mama Rose".

Post-Apocalypse
Nothing is known about Rose's life after the apocalypse, but she could have died before it even began. She might have survived the outbreak. Her husband might also be alive, but it is most likely that they are both dead, or reanimated.
