Corrected entry: The show is always described as Frank being the father of six children, but in season 4, his oldest daughter "Sammi" appears that Frank knew about, so technically he had seven children total (even though six grew up together in the house).

Correction: Franks explains to Sammi after the mother took her, he just forgot. So it's not an error. As far as us and Frank are concerned, he only had 6 kids. Frank only remembered he had another when he needed something from her. Which plays perfectly into Frank's character. So I think this should be removed as it is inaccurate.
