I can't find her obituary reference on Family Search. As far as I can tell, this is her FS profile:
All the obits listed here are family members and not hers. I was hoping we could identify the source that FS has for her obit, so that we could seek it on the other site. A lot of libraries provide free access to research tools that let you look at these records without paying for them. There are others that are paid sites but there are WikiTree members who are kind enough to use their membership to occasionally look up a few bits of information for you, if you can help them identify which site. The few links for her family members' obits are all on Genealogy Bank, so it's a good assumption that hers might be on there too.
If you can find the specific link to her obit from FS, please post it and it will help find it.
