The earliest mention of the village of Gaj dates from 1401 and concerns a dispute over it between the sons of Janusz from Jarogniewice and the widow of Andrzej from the village of Kowalskie and her sons. In 1475 Mikołaj from Błociszewo, burgrave of Kościan, bought the said village from Abraham Kiebłowski for 600 grzywnas. However, less than 35 years later it is noted in sources that the village was deserted. This state of affairs was changed by Wincenty Błociszewski (Mikołaj’s grandson), who rebuilt the desolate village and made it his main residence, from which he began to spell Gajewski. Thus the Gajewski family, of Ostoja coat of arms, descended from the Błociszewski family. Today in Gaj you can admire the historic manor house and the manor farm complex from the beginning of the 19th century, which includes, among others, a distillery from 1856, a sheepfold, a blacksmith’s shop, cowsheds and warehouses.
