Where to find the records
- Rock County official website
Hours, addresses and phone numbers for the county recorder, the district court and the Minnesota Historical Society, and any online record search the county offers.
- The county recorder
Deeds, mortgages and other land records from the county's beginning (the recorder was called the register of deeds until 1976). County birth and death records from 1870 on were first kept by the clerk of district court; in many counties they are now with the recorder, in others with the court administrator, and some recorders also have the marriage records.
- The district court
Civil and criminal cases, divorces and, in many counties, marriage licenses. Since Minnesota's courts were unified in the 1980s, probate (wills and estates) has been part of the district court as well.
- The Minnesota Historical Society
In St. Paul: many counties' older probate, tax, school and other records, the state censuses of 1865 to 1905, and statewide indexes to births (1900 to 1934) and deaths (1904 to 2001).

Boundaries and parent counties

Later formed partly from Rock County: Pipestone County
Records stay with the county that created them. If your ancestor lived here before 1857, search the parent county. The Atlas of Historical County Boundaries shows each boundary change.
Research tip
Minnesota took its own census in 1865, 1875, 1885, 1895 and 1905. They are indexed in the Historical Society's People Records Search (not every county appears in every year), and the 1905 census, like the 1895 census for men over 21, says how long each person had lived in the state and in the district, a clue to when a family arrived.
