In {{c|Batman Annual Vol 1 11]], the Penguin fell in love with an unnamed woman via the mail while in prison. When he was paroled, he dated her and even gave up crime for her. When he was re-jailed for technical parole violations, their romance continued remotely.

But I don't know what happened to her. As far as I know, she was never mentioned again (although the Penguin did join the Suicide Squad shortly afterward; maybe he was trying to get a reduced sentence to be with her).
