Olszowa [ɔlˈʂɔva] is a village in the administrative district of Gmina Ujazd, within Tomaszów Mazowiecki County, Łódź Voivodeship, in central Poland.

In 1406 Ścibor Bielina of Wola Drzazgowa bought Olszowa from Klemens of Wykno for 30 pieces of silver (grzywna).

Olszowa is also mentioned in 1429 when bishop Wojciech Jastrzębiec (on 5 September 1429 in Mnichowiec near Skierniewice) separated villages Olszowa and Popielawy from the parish of Małcz and on their basis and Ujazd, which newly obtained town rights (on 15 May 1428), created a new parish of Ujazd.

In a court record of Brzeziny district one can read that in 1471 Stanisław of Gutków and Olszowa was sentenced to reimburse Piotr the citizen of Ujazd with 43 grzywna, the value of cattle, horses, sown seeds and other things.

[6] His father was Marcin Olszowski who married Elżbieta Modrzewska a daughter of Andrzej Frycz Modrzewski (*1503-†1572).

With his second wife Zofia Dunin he had four sons: Andrzej, Hieronim, Zygmunt, Mikołaj and a daughter Katarzyna.

His other sons held important ranks but Andrzej Olszowski (*27 Jan. 1621 – †29 Aug. 1677) reached the position of archbishop of Gniezno and primate of Poland (1674–1677).

He had no heir and Olszowa was taken over by Wiktor Olszowski the son of Stanisław, castellan of Wieluń and grandson of Walerian's brother.

In 1916 the owner was already Bolesław Malcz,[11] the son of Julian and brother of Lucjan, a sublieutenant of a Polish unit of French Foreign Legion and World War I hero.

B. Malcz and his wife Leonia Zofia Wanda (born Moszyńska) had three children: sons Zbigniew and Stanisław and daughter Elżbieta (later known as Elzbieta Temple).

In 1906, during martial law in guberniya of Piotrków, he was sentenced to three months of prison for dictating the resolution of gmina Łazisko council,[12] in 1916 he was a member of a Social Care Council of Łódź district (Łódzka Okręgowa Rada Opiekuńcza), a member of the Sienkiewicz memorial committee[13] then a chairman of the board of fire brigade Ujazd (1917–1925).

The remaining building was used for some time as a shelter for a mobile cinema and room for village gatherings.

It contained three classrooms at ground floor, school office and two apartments of a schoolmaster and teacher upstairs.
