As with all illegitimate children, the baby will be born with the last name of the mother (Jones-Brown), but if Jenni marries Goodwin, it will be a Goode (assuming Jenni takes Goodwin's last name). If she doesn't marry him, then players have the option to go to City Hall and manually change the baby's last name to Goode. Some players also choose to give the baby yet another hyphenated last name, such as "Jones-Goode."
He can be somehow related to Smith Family from The Sims 2 and/or related to Jones family (The Sims 3).
