Maybe she was the last survivor of her planet, sent to Earth as a baby in a rocketship, found in a cornfield, and adopted by the O'Neill's (yeah, total Superman vibe)....

Or her mother was alien royalty who was exiled when the Kraang took over her planet, and fled to Earth...where she fell in love with Kirby O'Neill and, in the fullness of time, had a daughter. Perhaps her alien physiology broke down after too long on Earth and she died; perhaps, with regrets, she returned to her people to help fight the oncoming horde of Kraang, who now threatened her new homeworld (to say she is "lost" is a bit vague). The Kraang speak of April as "The One", which suggests a goddess, a prophet, or a princess.
