Entries from the surname index included at the front of Hendricks County Probate Order Book Volume 4 (15 May 1865 - 30 May 1868) have been added to the database Surname Index to Hendricks County Probate Order Books, which is on the Hendricks County GenWeb site. The surname index was compiled by the clerk at the time they were writing the entries. It includes the subject of the probate case, the type of case (estate, guardianship, etc.), and the corresponding book and page number.
This is an ongoing project - currently the surname index covers the years 1865-1891.
