I was trying to figure out how many generations could theoretically exist at the same time, so I decided to first check Guinness. Hopefully I did all the math correctly.

      I have family working on matching that one.

      Age when they had their first child:

      My grandma was 20, my aunt was 18, her son was 17, his daughter was 15, her daughter was 14, and her kid is now 6.

      6 generations.

      My grandma is 90. My great-grandma passed away at 99.

      Just one more teen pregnancy away from matching it.

    Well assuming everyone had kids at 18, and lived to 122, max is 6 generations.

    If everyone had kids very young, at 13, it maxes out at 9 generations.

      I think OP made an error in stating you had to be 18. The oldest living person ever was 122 (as indicated by Blamemeta). As long as you are allowed a few pre-18 births, you can get to 7 generations). At 15 years old you can get to 8 generations.
