There are quite a number of different family trees, but not much info on them visibly, I didn't open and look at each. You can access them on Ancestry at home if you have a membership. Your local library might have the Library version which you could access on their system with your library card.
As far as an obit: She might not have had one, depending on living family paying for one. A lot of elderly (she was about 95) don't have them due to no family members wishing to pay for one, no living circle of friends or family, not living in the area where they died long, or at at all, etc.
I would suggest contacting the cemetery. They might have some records. I have found obits, Death Certificates, burial permits; and a lot of the time, nothing. If they have the name of the funeral home, and it's still in business, try that avenue.
Not related, just cleaning up the mess in aisle four.
