So FB is probably birth of Ana (which would use Meegan as Tremaine), until death of Ana (which would use Gabrielle as Tremaine). Ella's parents probably appear, because Tremaine obviously had to know of Ella's dad if she married him after his wife died (assuming that's even what happened, considering this is Once).
