Jonas Foutley is the biological father to both Ginger and Carl. He is now the ex-husband of Lois. Jonas abandoned Lois and their children shortly after the birth of Carl. Ginger never had any fond or, for that matter, clear memories of her father, and all the photographs of him that are in her possession are of his leg.
In Hello Stranger, Jonas Foutley is Ginger and Carl's father, 31 years old, and he lives in an apartment, which is where Carl's male friend, Hoodsey never been in before. Although he never returns her call, she convinces herself that he will show up. Lois, however, rightly believes that he will not appear. Lois is in the hospital at the time of Ginger's performance, and has sunflowers sent to the school with a card signed "Dad", but Ginger figures that Lois sent the flowers and her father let her down.
In An "Even Steven" Holiday Special, Jonas is shown performing as Santa Claus, standing on the street corner, collecting money, and happens to come across Carl and Hoodsey. Hoodsey believes that Jonas is really Santa Claus, and confides in him that Carl does not believe in Santa, because Santa has never granted him his only wish (to have his father home for Christmas). After hearing this, Jonas decides to pay the Foutleys a visit, which somewhat improved his relationship with his children (but not really with Lois).
Though Jonas never really becomes a fixture in the family, he appears sometimes to bequeath fatherly advice to Ginger, and to teach her about the extended family from which she is descended. Carl, however, seems to remain bitter, and limits the majority of his contact with Jonas and Lois seems to have mixed feelings with the whole situation.
Jonas is described as an "animal lover" and has a pet dog named Ben.
Ginger shares a close bond with Jonas. She never shows any resentment towards Jonas for his actions of flaking and abandoning the family. Ginger usually calls Jonas for advice or to know more about her family ("Losing Nana Bishop"). When Ginger has appendicitis, Jonas visited her at the hospital and delivered her a batch of sunflowers and comforted her when she was in bed.
At first, Carl shows resentment towards Jonas early on in the series as he couldn't forgive Jonas for leaving the family. He also showed bitterness due to Jonas never visiting the family, which was Carl's Christmas wish every year. In "A Lesson in Tightropes", Carl is angry that Jonas visited Ginger at the hospital and for Lois spending time with him, which makes him think that Lois will lose her love for Dr. Dave. However, in "Ten Chairs", Dr. Dave convinces Carl to forgive Jonas and the two begin a new relationship.
Harold is a co-worker of Jonas when they both dress up as Santa Claus for the holidays. Harold shares his short history of having kids when Jonas asked if he had children of his own. He also told Jonas "to go in peace", showing that Harold is peaceful guy.
Lois and Jonas met sometime around the 1980s and settled down. They clearly loved each other to the point where Jonas would record tons of home movies and becoming a father of two before shortly leaving them.
