It is claimed by some sources that Ogiński was born in
Guzów in
Mazovia (west of
Warsaw) in the
Kingdom of Poland. Nevertheless, in 2025 Lithuanian researchers found records in metrics of the
Salantai Church of the Assumption where it is stated that Ogiński was born in the surroundings of Salantai (present-day
Kretinga District Municipality of
Lithuania) and was
baptized in the Salantai Church of the Assumption. His father, Andrzej, was a
Polish-
Lithuanian nobleman from the
Ogiński family and
Trakai governor of the
Grand Duchy of Lithuania. Hence, some sources indicate that Michał Ogiński was
Lithuanian. His mother, Paulina Szembek (1740–1797), was the daughter of Polish
magnate, Marek
Szembek, whose ancestors were Austrian, and Jadwiga Rudnicka, who was of Lithuanian descent. His first introduction to music arose during a visit to relatives at
Słonim where
Michał Kazimierz Ogiński had a contemporary European theatre that hosted opera and ballet productions. Michał Kleofas received an
Enlightenment gentleman's education. He studied music with
Józef Kozłowski and took violin lessons from
Giovanni Battista Viotti,
Pierre Baillot, and
Ivan Mane Jarnović. Since his father's diplomatic mission to
Vienna in 1772, the prince's tutor was Jean Rolay, later tutor to Emperor
Leopold II. Michał Kleofas learned French, German and Latin. Years later, Ogiński erected a monument to his tutor at the
palace in Zaliessie as a token of his gratitude. Michał Kleofas had an older sister, Józefa, and half-brothers, his mother's sons from previous marriages:
Feliks Łubieński and
Antoni Protazy Potocki. ==Career==
