St. Genevieve County is located on the Mississippi River below St. Louis, Missouri. This area was settled sometime between 1735 and 1750 by the French who brought with them a priest of the Roman Catholic Church. In the beginning, this area was part of the Illinois County and it is generally accepted to be all the land claimed by the French from the mouth of the Ohio River north to the Great Lakes which includes the valleys of the Mississippi, Missouri and Ohio Rivers. At this early time the seat of government was in New Orleans and this part of Missouri was part of the Upper Louisiana Territory. In 1803, when President Jefferson made the Louisiana Purchase, all of this territory was included in that transaction.
