- Mrs. Morgan - Jenna's mother who picks her up from school, and helped sew the clothes for the school play.
- Mr. Morgan - Jenna's father who helps her with her condition.
- Grandfather - Mentioned in "Jenna's Bedtime Blues".
- Binky Barnes - In "Muffy's New Best Friend", it showed Jenna and Binky playing soccer together. The episode also showed Jenna and Binky having the same taste in movies. In "Binky Goes Nuts", Jenna helps Binky with his allergies, and goes out of her way to help him study them. She also showed concern for his well being when he accidentally consumed peanut products.
- Francine Frensky - Even though it seemed that Francine made Jenna feel guilty about the 'Athlete of the Year' award in "The Good Sport", in the end, Francine made up with Jenna. After that, Francine and Jenna became good friends. In "Jenna's Bedtime Blues", Francine was even able to pull some strings to get Muffy to invite Jenna to her sleepover. Francine is also the only friend who knows Jenna's real secret that she wets the bed and understands because she used to suffer from it, too.
- George Lundgren - In "Buster Makes the Grade", Jenna was at the Sugar Bowl with George and Alex. They were seen having lunch together in "Don't Ask Muffy". At Muffy's sleepover, she made up the idea that she had a crush on George to make it seem like it was her deep, dark secret. She also had invited him to her birthday party.
- Buster Baxter - In "Buster Makes the Grade", Jenna invites Buster to have an ice cream with her.
- Alex - Jenna is seen with Alex in a number of episodes, like "Buster Makes the Grade".
- Maria - Jenna has been seen with Maria many times, usually in class, but also outside of school, too. Jenna has private conversations with Maria and has her over to her house in "Maria Speaks," possibly suggesting a close friendship.
- Helen - Jenna is seen with her in the library while they are reading Henry Skreever books to each other and talking about it.
In season 1, she was used as a background character and only spoke once (and was a short line) Fern and Sue Ellen) from seasons 2-9 and had several episodes where she made major appearances in. "Messy Dress Mess" was the first time Jenna has spoken since "Binky Goes Nuts.". After that, she was a main character (making appearances like

Postcards from Buster
- Jenna hates hockey because she thinks it is dumb.
- Jenna plays badminton and is the badminton champion.
- Jenna helped coach pee-wee soccer.
- Jenna helps with the wheelchair basket
- Jenna won the athlete of the year award.
- It is revealed in "Jenna's Bedtime Blues" that she suffers from nocturnal enuresis (bed-wetting).
- Jenna is midfielder for the Lakewood Elementary Soccer Team.
- She is allergic to milk (as revealed in "Binky Goes Nuts"). This means that her immune system overreacts to milk, potentially causing anaphylaxis. This is different from lactose-intolerance, where people simply lose the ability to digest milk sugar.
- She spoke for the first time by saying "Hey Buster, how's it going? Grab a stool." in "Buster Makes the Grade."
- The last time she was heard properly speaking, until season 18, was the episode "Binky Goes Nuts."
- Seeing as her father wet the bed as a kid, and that bed wetting can be genetic, it's revealed she inherited her nocturnal enuresis from him.
