The first recorded mention of “Kociewie” dates to February 10, 1807. The Słownik Geograficzny translation from 1895 indicates that the name “Kowiecie” likely comes from the numerous swamps and marshes surrounding the mountains. The soil was described as being fertile and the area was primarily an agricultural area – crops included wheat, rye, barley, oats, peas and turnips.
