Vigo County, IN
History
The area in present-day Vigo County was first placed under local jurisdiction in 1790, when Knox County was created. This all-encompassing county was repeatedly subdivided as its lands were occupied − on 30 December 1816 a portion was partitioned to create Sullivan County, and on 21 January 1818 the northern portion of Sullivan was partitioned off to create Vigo County. The first county commissioners organized the government in 1818, including naming Terre Haute as its seat. The county's borders changed several times; in 1821, part of the county was formed into Parke County, and later that year Putnam County was formed which also affected Vigo's borders. The final change came in 1873 when the present boundaries were defined. The county is named for Colonel Francis Vigo, of Italian heritage but a citizen of Spain due to residence in St. Louis. He is credited with assisting George Rogers Clark, both in financing Clark's exploration and American Revolutionary War efforts, and in service as an agent obtaining military information for Clark against British campaigns on the then frontier.Source: Wikipedia
