In the manga universe, it's Ruby who's from Johto, and whose father is Norman. Sapphire is Birch's daughter.
In the anime, no one's from Johto, Brandon not real. May is Norman's daughter.
In the games, the protag is from Johto AND Norman's kid, while the rival is Birch's kid.
So no to answer OP's question, no, she isn't.
i like manga canon most
