one thing that upsets me regarding timelines... why would her grandmother be a whopping 92? that makes her parents be about 50 OR OLDER. its hard but not impossible to birth a child at 50 but this makes grandma be about 40or something when SHE gave birth which back then was just not heard of. I would have made it a great grandmother or a great aunt. or grandmother but just lower the age.
Ruby Rose Her mom is younger than her dad... but like you said it isn't unheard of for someone to have a child at 50 years in age. It also did say that the dad was the youngest child in his family... so I think that the ages are fine.
