Good fortune.

Some Googling this morning yielded some worthwhile results, including three new links I've included: Darke County Infirmary Data, Darke County Local Government Records (Wright State U.), and the Ohio History Online Portal... I've discovered that the records at Wright State include a Day Book for Darke County Infirmary during the time of Annie's stay there. I'm hoping that access to these sources will help reveal useful details.
