Longest family tree?

My longest was 12 before my game (and whole save file) exploded. I tried to recover it for a long while then just gave up because the headache of fixing it (after hours/days/weeks of trying) just wasn't worth it anymore, so now I'm working on gen 1 of a (hopefully long term legacy) I have no set ending point. Will start as a 10 generation challenge (with alphabetcy naming conventions) and progress, if possible to a 26 gen alphabetcy. If I make it there without issues or save crashes, I'll see how much farther I can get. The ultimate goal is to hit the 100 gen achievement but so far, 12 is my record.

Since the irritation of my failed legacy explosion, I've taken steps to back up and create copies of my family save (which I will update periodically to make sure I have the newest version of my legacy on hand in case of further problems. *crosses fingers not to need the backups*
