In my last family I played, I almost have the whole town connected to another family. So here's how it done:
First you have to have the Family of six. Trust me on this: Two young adults, two teens, and two kids. You can use cheat if you please.
You have to have one of them hook up with another family, get married, have kids.
Then the next set have to do the same thing, fall in love, get married, make kids, and so one.
Until all the family in town is related to the first household. Sound easy huh.
