Really? I'm not the only insane one? I already completed my 13 generations and then cheated and got Rowan alien impregnated for the 14th.
Okay. I am insane.
Evidently not. Although I'm only on third generation - Charlotte. She has a twin brother, Phillip - a name I randomly picked off of the family tree and modified. Did you use Julien as a generation?
As it happened on generation 8 a boy was born first, so he became Julien. I made him a romance sim and he did father quite a few children, but none incestually.
Actually, if I was really doing this right, instead of getting Rowan alien-impregnated I would have gotten her husband to father a child first, but I decided 13 generations was enough and skipped that part. My biggest challenge was that in generation 5 I had 6 boys before a girl was born to be Marie Claudette (I know I could have replayed the birth until I got the result I wanted but that felt too much like cheating).
No, they're still sitting in my "Mayfair" neighbourhood. I don't upload much, since it rarely gets noticed or downloaded. If you're interested, I upload them for you. It'll probably take a few days though since I'm procrastinating over a 4000 word essay draft currently.
I used a new, empty, neighborhood and made the townies out of non-heir siblings. Weird I know, but it kept character count down. I used very inaccurate houses. While I have basically completed the family I would be interested in your Mayfair houses too.
