Miami County Overview
Miami County Death Index at Probate Court
The Miami County Probate Court has a genealogy and public records section that includes death records from 1867 to 1908. Ohio required death registration starting in 1867, and Miami County has records from that first year. These early entries are handwritten in large ledger books. Each typically lists the name of the deceased, date of death, age, cause of death, and place of birth. Parents' names appear on some entries, mainly for children.
The Probate Court is in the courthouse in Troy. Walk-in visits during business hours are the best way to search older records. Staff can assist you in locating specific entries if you have a name and an approximate date. The records are not digitized, so in-person research is necessary for these early volumes. You can also write to the court with a specific request.
Here is the Miami County Probate Court genealogy and public records page.
That page details what records are available and how to access the Miami County Probate Court's genealogy collection. Estate files, wills, and guardianship records are also available at the court and sometimes contain references to deaths.
