How do you pick names for your Sims?

I usually randomize the starting Sim's name but from then on, I go with the other options listed above. For some reason, I have this habit of naming everyone in a particular household so they have the same initials. I also use variations of the parents' names for the kids (i.e. Hank would have a son named Henry, ect). I also name the sims based on their parents interests. If I have a musical sim, I'll name their kids something musical like Lyric, and sometimes their pets as well. In my Westbrook legacy rotation, one of my sims was an artist, and I named their calico cat Picasso. Her daughter is a musician like her dad, and she had a cat named Sebastian for Bach. So it all really depends on the mood, the family, and what's easier. By the time my sims get married, I usually have a name for a male or female that would best represent the family.
