WELCOME This RCGS web page provides an alphabetized list of land owners found in the 1922 Rock County, Wisconsin Plat Map. Links to the all-names index and to images of each of the 20 Rock County Townships are below; once you find an ancestor's name in the index, note the Township name, then click on the corresponding map image link to view the exact location as well as neighbors' names, surface water, railroad lines and nearby churches, schools, cemeteries, villages and cities.
SOURCE INFORMATION Plat Book of Rock County, Wisconsin, published by W. W. Hixon & Co., Rockford, IL, 22 June 1922 (hand dated), distributed by Gazette Printing Company, Janesville, WI (hand signed by E. R. Adamson). This information was abstracted and transcribed in Dec., 2006 by David and Janet Bradford, RCGS volunteers (Index Copyrighted 2007 by RCGS).
- Plat maps list land owners of record; but your ancestor will not be listed in this index if they rented land (e.g., tennant farmer). Converely, an absentee landlord listed in thie index may have lived somewhere else entirely and therefore not found in other contemporaneous records like the 1920 US Census.
- Most land owners' names are clearly displayed in the Plat Map and transcribed to this index, but parcels under 10 acres sometimes just show owner's initials. If only initials are displayed on the plat map, then the index will also show these initials and provide possible matching surnames of a nearby land owner(s) in the Notes column of the index (ex.: land owner "A. S" may have a note stating, "Smith, Schultz & Simonson surnames are found nearby").
- Some parcels are owned by more than one party; for example, "Smith & Jones" are listed twice in the Index (once under "Smith" and again under "Jones").
- Some people owned multiple adjoining parcels in the same section. In these cases, owners are listed once and the acreage is summed to reflect their total holdings in that township section. Non-adjacent parcels are listed individually.
- Some names on the Plat Map were not clear and legible. When possible, the 1920 US Federal Census or RCGS Probate Index (for estate parcels) was used to determine the name. In some cases, several alternative spellings are shown for partially legible plat map names. For example, if we could not tell if the name was "Gleason" or "Reason", the index will have an entry for both: "Gleason or Reason" in ther G area and "Reason or Gleason" in the R area of the Index).
- Finally, a word of caution about spelling consistency: there is none, so be sure to check all spelling variations for your ancestors' names. Names from this Plat Map sometimes appeared several times, each with a different spelling. At this late date (85 years after publication), it is difficult to determine whether these spelling variations reflect the original mapmakers' transcription errors, intentional changes by individual owners who anglicized their name over time as they acquired land, or generational surname evolution (e.g., "Frederick Schumacher" who may have been the father of nearby "Fred Shoemaker"). The index below attempts to faithfully transcribe the names exactly as shown on the original Plat Map. Even the most glaringly apparent errors are transcribed exactly as shown on the plat map and without correction in this index. That is not to say that the Index is error-free; doubtless, with over 35,000 data entries for 6,200 land owners, we have inadvertantly misinterpreted, mis-typed, or mis-labeled a few Index entries - we welcome corrections of any errors we may have introduced.
