Retired Sims stories retrieval? Sim family tree app?

Does anyone know of any trick to find out the stories of your retired Sims on Sims Mobile? I was getting really confused about who was who with all the babies in the house and started writing down the story info and connections this evening. But I have 5th and 6th generations currently in the household and cannot remember the other parent on a few because the parent that was my Sim is retired. Not to mention I have no idea anymore from the 1st-3rd generations. I just made things up for fun but it sure would be useful to be able to at least pull up a current Sim’s parentage (-adoptionage) at any time, playable, non-playable or retired and moved out, from the family photo.

Also- I can’t find a mobile app for fake family trees. Anyone use one they like? I found a web based one for Sims- called something like plumbob tree that I will try but would love to do it on my phone where my screenshots are. Ideas?
