He graduated in law from the Albertina University of Königsberg, and became an assessor at the Civil Tribunal, and then a sub-prosecutor at the Court of Appeal of the Duchy of Warsaw.

He had a younger sister, Dominika Józefa Cyryla (c. 1783 – after 1821), the wife of Grzegorz Domański (a laborer and former soldier); and brothers Bruno Placyd Franciszek (born 1786) and Ferdynand (1788–1827), owner of Masłomiąca.

After the death of Maciej Tarczewski, Marceli's mother Józefa married Wincenty Ferreriusz Kraszewski (c. 1752–1830), the ensign of the National Cavalry.

[2] In 1820, together with Jan Olrych Szaniecki, he made an unsuccessful attempt to establish an agricultural and commercial association in Pińczów.

The project of this organization later became the prototype of the Land Credit Society (Towarzystwo Kredytowe Ziemskie) established by Franciszek Ksawery Drucki-Lubecki.

The printing house issued one hundred and sixteen items within ten years, including the series of Polish Writers' Library (nineteen volumes) and the Themis legal magazine.

[2] In May 1827, Tarczewski bought the indebted estates of Komorów and Sokołów, with the foundation privileges of the parish in Pęcice, from Ignacy Sobolewski, the Minister of Justice of the Kingdom of Poland.

For firm statements in this trial, Tarczewski was punished with a reprimand, accused of the offence of prosecutor Onufry Wyczechowski.

After the outbreak of the November Uprising, on 29 December 1830, dictator Józef Chłopicki appointed Tarczewski to a commission that was to recognize documents concerning people suspected of spying.

From 1835, he headed the Legal Section in the Government Commission of Internal and Spiritual Affairs (Komisja Rządowa Spraw Wewnętrznych i Duchownych).

[2] Tarczewski was the co-author of the Regulations in Force When Carrying Out Court Medical Investigations on Corpses (Przepisy obowiązujące przy wykonaniu sądowo lekarskich dochodzeń na trupach , 1840).

[2] Tarczewski was married to his cousin Aleksandra née Tańska (1792–1850), the daughter of Ignacy Tański and Marianna née Czempińska, contributor to magazine Rozrywki dla Dzieci (Entertainment for Children), co-founder of the Union of Patriotic Charity of the Varsovian (Związek Dobroczynności Patriotycznej Warszawianek) during the November Uprising.

Marceli and Aleksandra Tarczewscy had twelve children (of whom more than half died in childhood or early youth): Ignacy Juliusz (1818–1819), Władysław Wojciech Jozafat (born 1819), Helena Katarzyna (1820–1845), the wife of Aleksander Radwan, real state councilor; Kazimierz Maciej (1822–1872), an official of the Bank of Poland; Gustaw Jan (1822 – after 1864), a staff cavalry master of the Russian army who was the organizer of the uprising in Biała Podlaska, for which he was sent to exile; Maria Stefania (born in 1823), married to Józef Konstanty Grodzicki; Marcjana Stanisław Jana de Matha (born 1825); Ignacy Onufry Antoni (1826–1829); Maria Regina (1826–1827); Maria Klementyna (1828–1828); Aleksandra Wincent (1830–1836) and Adam Jan Hieronim (1832–1833).
