Mrs Jacobs
In some universes, Mrs Jacobs was the adopted mother of Jenny Everywhere, being married to Simon Jacobs and also the mother of Jenny's adopted sisters Julie and Jordan.
In one such universe, the Jacobses lived in Westbrook, Wisconsin. Mrs Jacobs was the wife of Simon Jacobs and mother to three adopted daughters: Julie, Jenny and Jordan. This Jenny was none other than the local incarnation of Jenny Everywhere, and at some point Simon and his wife became aware of their daughter's shifting abilities, although it is unclear whether they knew about Jenny's own nature as a multidimensional being. (COMIC: The Jenny Everywhere Chronicles) In most other universes with this family setup, on the other hand, the Jacobs parents were in the dark about Jenny's powers, unlike Julie and Jordan. (COMIC: The Mind of Jenny Everywhere) Jenny' mother was fussier and more concerned about the dangers to which Jenny exposed herself than the more laid-back Simon.
She was an average cook; although capable of a decent meatloaf surprise, she had a bad enough track record with trying new dishes that when presented with the latter, Julie jokingly asked if the “surprise” was its being actually good. Mrs Jacobs received this joke in good humour. (COMIC: The Jenny Everywhere Chronicles)
