How old is Alice?

If Alice was Alma's older sister, and was involved enough in Project Origin for Alma to come after her, then how old must she be? Alice appears to be very young, maybe mid-thirties at the most. But Paxton Fettel isn't exactly a child and Alma's project would have had to have ended over 10 years ago. And for Alice to have been old enough to participate in Project Origin, she would have had to have been an adult. So, how old exactly is she? She looks much too young to have been a part of Project Origin, yet her name is listed as being involved and Alma is actively seeking her.
