I chose the last choice as the closest to what I feel are the right age ranges:
Julie, Eric, EJ, Jan, Belle, Will, Chanel, Carver
Julie is obviously the oldest of this group, with Carver as a baby as clearly the youngest. Chanel is the next youngest as the newest young adult and in the same age category as Johnny and Allie, who are younger than Will. Also, Will is the next youngest as he was born after Belle and he was not SORAsed when she and Philip were. The question to me would be who's older, Eric or EJ, EJ was SORASed putting him in the same age group as Eric and Sami. Jan and Belle were classmates so it's not clear which one is older.
