I see that her place of birth was listed as United States...and her birth date as 1892. That seemed on the early side for being born in the USA from the family from Altavilla that I have seen. I found her in the Illinois Deaths and Stillbirths index on FamilySearch and it says she was born in Altavilla.
I believe I also found a matching birth record in Altavilla.
Actual date of birth varies slightly, but given the time period that is common.
