Oliva Erwin who married Jeremiah Swing in Cincinnati, Ohio on July 26, 1827. HELP find her parents please!

Hi Amy, thank you for your interest. I do not know where she died, I saw this 1874  death date on a  Swing family web site, but the family member who put it up has since died.  The name on the 1870 census was Oliva Swing, Hancock County Ill. I checked the Illinois statewide death index pre-1916 but did not find her. I think 1874 was too early to be recorded. My family has recorded all the other family lines so to have this one left out is very intriguing! She was listed on my family research papers as only "Olive"! My father told me that this side of my family was French-Canadian and Mr. Swing was from a French family, so I wonder if Olivia could be from a Canadian family.  There is also a possible Indian relative in my family, so maybe she is the one, although she is listed as white in the census records. Her son is in the 1900 census in Peoria, Ill. but she does not appear there.
