Simon Jacobs
In some universes, Simon Jacobs and his his wife were the adopted parents of Jenny Everywhere, with Julie Jacobs and Jordan Jacobs as Jenny's adopted sisters.
In one such universe, the Jacobses lived in Westbrook, Wisconsin. Simon was a tinkerer as a hobby, often staying up late in the Jacobs house's garage building something or other. 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. Simon was also aware of Jenny's superhero exploits, and indeed, not always as secretive about them as Jenny might have hoped, although he still kept the secret as such.

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)
When the Jenny Everywhere of another world entirely got shifter hangover after overexerting her powers, she got ghost-memories slipping through from many other Jennies. One of them was of her father's workshop in Wisconsin, with her getting a glimpse of the father in question, being confused by the fact that he was a white guy. (PROSE: Morning After)
