The recent
Dark Matter tv series (which I understand is based on a graphic novel, but I've not been able to find it) features six people waking up from stasis on a starship in flight, with no memories of who they are or how they got there. They even call themselves by the numbers One through Six, in the order they awoke, in lieu of names.
The rest of the series is essentially their working out who they used to be and dealing with how that differs from who they have become.
