They're not the same. Everett Ross and Thadius Ross have separate identities and storylines in the comics. Their powers, if any, and character arcs are completely different.
I'm not sure specifically who 'ann b ross' is just from this phrase. It could be an author. Maybe it's someone who has created works within the realm of 'fantastic fiction' which might include elements like magic, otherworldly beings, or extraordinary adventures.
I'm not sure specifically as there could be many novels named 'amelia'. It might be about a character named Amelia, perhaps her life journey, her relationships, or some challenges she faces.
No, Amelia Bedelia is typically considered fictional and humorous rather than realistic. Her misunderstandings and comical actions set it apart from realistic fiction.
The Betsy Ross story is based on historical accounts and tradition. However, historians continue to debate and research certain elements, so we can't be completely certain of its absolute truth.
