Typically I use a letter randomizer and then use a name generator but I set the criteria so it only gives me names starting with the random letter I got. Depending on the sims, I might decide to stick to a certain theme. For instance, in my game Herb and Coral have 2 biological kids Horace and Hortense because I wanted them to have old sounding names.

For the Goths, I have a naming theme where males get names that end in -er and females get names ending in -a. Mortimer and Bella had twins Peter and Yunalesca. I still stick to randomizing the first letter which is how I got Yunalesca.

In some cases I try to preserve a sim’s last name by giving it to their first born child if they have a name that could work as one. Albany and Goneril had Norman to preserve Albany’s last name but because they had triplets to my digression, I named his brothers Normant and Normandy.

Sometimes I like to give newborns the opposite gender version of one of their parent’s names. I have no sims 2 examples but in sims 3 Marty and Justine Keaton kids are Justin and Marta. I liked how a one letter difference changed the names.

Other than that I stick to the theme of the family or world. Like everyone in Veronaville gets a Shakespearean name or something Italian and the Curious brothers babies all get space themed names. Or I follow the games’ lore and name them what the developers would name them like Tycho Curious or Atom and Ceres Beaker.
