There is a brief mention of the death of Amelia Graham in the Milwaukee Journal, Wednesday, December 21, 1892:
Mrs. Amelia Graham, aged 52 years, died this morning. The funeral will take place at 60 Jackson Street Friday at 8:30 am.
The age fits the range you gave; is the address familiar?
I got this through the 19th Century Newspapers database which is accessible through a (premium) subscription to Godfery.org.
Hope this is your Amelia!
