Redi Jōjī (Lady Georgie) - 45 episodes based on the manga, "Georgie" written by Mann Izawa and drawn by Yumiko Iragashi status: dropped
Georgie learns that she is an adopted daughter and that both her brothers have fallen in love with her. She flee Australia to look for her real father and her lost love in England. I've only seen a couple of episodes of the dubbed version in our local channel I guess around 5 years ago. It was a jolt in my head when I suddenly remembered the story and I have to look up for the title as I've forgotten it. This might be one of the earliest form of reverse harem. The manga debuted in 1982 while the anime aired the following year.
