The oldest mention of Modliszewo (Modliszewka) comes from a document by prince Władysław, issued in 1316, in which Andreas de Modlizevo is mentioned. There was a church in Modliszewo (Modliszewko) already in the second half of the 14th century. In 1380, the Gniezno official settled the dispute between Maciej, the parish priest from Modliszew Mały, and the heirs of Modliszewko Wielki. In the years 1395–1401, Piechno of Modliszewo, castellan of Czarnków, performed. His spouse was Małgorzata. According to prof. W. Dworzaczek may have belonged to the Ostoje family. In 1401, the Gniezno official testified that Paweł from Jabłkowo, the parish priest in Modliszewo, cleared the charge of raping Magda of Modliszewo. In 1414, Jan, the parson of Modliszewo, appeared as a witness in the tithing case in Mieleszyn.

The first Modliszewski who can be associated with the heraldic Clan Ostoja, was Marcin Sitek, heir in Lesser Modliszewo, who in 1451 framed his wife Małgorzata in the amount of 40 fines on half of his parts in this village. Between him and Marcin of Wielki Modliszew, Dryja coat of arms, in 1461 a bid bond was established that they would live in peace. In 1464, Fr.
