Rosa comes from a Cuban family. Her great great muggle grandpa and grandmother migrated to England when they noticed their son (her great grandpa) was acting a bit strange in his younger years. They feared their own child not knowing it was magical powers, they left him with a witch doctor and left the country as to not have a family curse take over. When her grandmother and her father neither had magical powers they were content on settling down. However, Rosa's father noticed her powers blooming and believed the family curse was appearing again. He, however, was not ready to give up on his daughter. He researched day and night until he found Hogwarts. Deciding it was the only option, he enrolled his daughter. However because of the secrecy needed to be kept, he and the rest of Rosa's family just believe she is enrolled in a private institution.
