She was born sometime in the 1920s, Jessica gave Martha Kent, her daughter-in-law, a necklace on her wedding day.
After Louise McCallum was killed on June 17, 1961, her accused murderer "Joe" came across Hiram and his wife Jessica at the Kent Farm. Jessica gave Joe one of Hiram's jackets so he wouldn't stand out. Before leaving the farm with Joe, Hiram said goodbye to Jessica and their unborn child "Gene" but she insisted his name would be Jonathan.
- Clark told Jonathan what Hiram told "Joe" and suggested that Jonathan and Martha were chosen by Jor-El to raise him because of the love that he felt at the Kent Farm.
- Kendall Cross also played a little girl's mother in Season One's Jitters and supplied the voice of Lara-El in Season Three's Memoria.
- Jessica Kent has the same initials as her son Jonathan Kent: J.K.
