September 12, 1913 The Settlement of Swan Valley

The current Swan Valley City officials and Chamber of Commerce say Swan Valley was settled before 1900, but this says it was not founded as a town until 1913.  Is there a distinction between settling and founding? When the Swan Valley area was “settled” was it called something else?  Was Rainey Dell the center of the settlement prior to 1900?  

-Here’s an article from the Idaho Republican newspaper, September 12, 1913 about the declaration of settlement in Swan Valley.
