"Poe no Ichizoku" has 15 episodes. The story begins in 1744, but
as you can see from List of Hagio titles,
Hagio Moto didn't write the episodes in chronological order.
Edar and Marybell were illegitimate children of Earl Evans.
They were abandoned in the forest and discovered by Old Hannah,
who was a Vampanella, which means a vampire in "Poe no Ichizoku".
Old Hannah brought them up. When Edgar was eleven, he got to know
the secret that Old Hanna and people in the mansion were Vampanellas.
He was forced to promise he would turn into a Vampanella, a family
member of Poe, when he
became an adult. He parted with Marybell, who was adopted.
When he was 14 years of age, Old Hannah was killed by a villager
and the villagers got to know the secret of the mansion.
Edgar was taken into the family of Poe before the family escaped from
the villagers.
Three years later, Earl Evans' eldest son Oswald met Marybell and Edgar.
Knowing Edgar was a Vampanella, Marybell decided to kill him. However,
she changed her mind when she knew Edgar kept being nice and loving her
very much. Edgar took her into the family of Poe.
