1.She is not listed in the on-line transcription of the Omro Junction Cemetery, so I would suggest contacting the city to learn if she is buried in the Omro Cemetery. http://www.omro-wi.com/cemetery.htmlhttp://www.omro-wi.com/cemetery.html
2.Her death is not listed in the Wisconsin Historical Society genealogy vital records index.You might try contacting the Winnebago County courthouse in Oshkosh; they sometimes have records that were not reported to the state.
3.Her death is not listed in the on-line Oshkosh Public Library Vital Records Index, so it was not reported in the Oshkosh newspaper.
If you have a public library nearby that has a microfilm reader, your library can request microfilm of the 1875 & 1876 Omro Weekly Journal.It will be sent to your library from the Wisconsin Historical Society.Typically the loan period is about 3 weeks.You'd have to read every issue, but it is a weekly newspaper and the local news is usually only on two pages of each issue.
