Generations and Fam Tree Question

I'm sorry to hear that. The only time I played to a tenth generation was when I was doing the Pinstar Legacy Challenge. Then, I created forms for myself so that I could keep track of certain achievements that would reap points at the end. But more importantly, I had the generations listed. I know of no way to go back, unless you've kept earlier saves of your game. Unless you can pull from your memory the names of the lineage (direct line) of your Sims. Perhaps, someone else will come along with an answer for you.

Did the culling happen before or after the November 2017 patch? If it happened after, the culled sims should still appear in the family tree.
But yes, there are no other way to see how many generations you have had. Not even achievements that require 26 and 100 generations doesn't show it. Only those that require 10 generations.

I'm afraid it happened before. I've been playing the same family line for a really, really long time! I was hoping there could be some sort of game cheat or something to reveal that. Oh well. I guess i'm sol :(

If you click up higher on the tree, you see the previous generations. I'm on the tenth generation, and I can see all the way back to the two matriarchs of the family. All of the ghosts are eventually culled, but they're still in the tree. You can also grab and move the tree on the screen to reveal more generations.

Invisiblgirl, unfortunately for me I don't have that option. The thumbnails are just blank or not even there after a few generations back.

Check your Achievements. There's one for Alphabet Legacy that tracks upto 26 gen, I believe, maybe one longer than that.
