Founder of the town. The greatest coloniser of the Bracław Pobereże: 170 towns, 740 villages, 12 starostwa. Built the fortress of Kodak, the castle at Brody. Married to Krystyna Lubomirska (1619) — a connection that, a century later, would determine the fate of the estate.

27 February 1637. — received from King Władysław IV a privilege for the foundation of 8 towns under Magdeburg law «for the defence of the Kingdom upon the Kuczmański Trail, in the voivodeship of Bracław». The document is a form-template with blank spaces for the names: «z okienkami, na wpisanie przezwiska Miast, które sadzone będą». Miastkivka, most probably, — one of these eight townships.

Son of Stanisław. Through his marriage to Joanna Barbara Zamoyska (1642, dowry of 800,000 zlotys) he annexed Szarogród, Krasne, Raszków. It was he who in 1646–47 seized the khutir of Subotiv from Bohdan Khmelnytsky — one of the causes of the Cossack uprising.

In the hearth-tax register of 1664, Miastkivka is still entered as «p. Koniecpolskiego, wojewodzica Sędomirskiego» — although Aleksander had died in 1659. The actual owner — his son Stanisław Samuel.

The last of the main line of the family. Childless. Before his death he passed all his estates to his cousin Jan Aleksander. In his register c. 1672 (Connotatio Dobr) Miastkivka appears — in the Bug Tract (income 42,000 zlotys/year), and Kamionobrod — in the Dniester Tract. The two tracts together — 77 towns, 50 villages.

Childless. At his funeral the heraldic shields were «broken» — the rite of a family's extinction. The Ukrainian estates were largely laid waste after the Ottoman occupation (1672–1699).

Sotnyk of the Miastkivka sotnia in the 1649 Register (259 Cossacks). In 1654 Paul of Aleppo sees him as «colonel Michaił», stationed with his host «to keep watch over the border of the land of the Lachs, of Moldavia and of the land of the Tatars». Colonel of Bracław until c. 1666.

Formally Miastkivka — property of the Koniecpolskis. But the real authority — with the Cossack colonel: justice, defence, administration. The Koniecpolskis are far away; the fortress — is here.

Son of Mykhailo. Miastkivka — «his estate» (Lehun).

In 1708 he rebuilt in stone the Church of the Annunciation — the very one Paul of Aleppo had seen in 1654. Walls a sazhen thick (~2 m), originally with 4 domes. The church withstood seven burnings by the Tatars — and stands to this day.

Presented a Gospel (printed at the Kyiv-Pechersk Lavra, 1697) with the inscription: «given to the town of Miastkivka, his estate, for the church of the Annunciation, in the year 1708».

After Poltava (1709) exiled to Siberia as a Mazepist. Local tradition of the late 18th century maintained that the town was «founded at the end of the 16th c. by colonel Zelenskyi» — Cossack memory had erased the szlachta Koniecpolskis.

The first Lubomirski to acquire the Miastkivka key. About 1724 he took over the estates of the extinct Koniecpolski family. In 1744 the Lublin Tribunal confirmed his ownership against the claims of the Chałaims.

The entire estate-complex was called «the Krasne latifundium» — 7 keys, stretching from 3 miles beyond Vinnytsia to Yahorlyk on the border, across three districts. The towns: Busha, Raszków, Józefgród, Savran, Chechelnyk, Tsekinivka, Kruta, Miastkivka, Rybnytsia, Tomaszpol — «surrounded by countless villages, slobody and khutory». Before 1672 the count here was 61 townships and 99 villages.

On the death of Jerzy Aleksander (1735) his estates were divided between his two sons: Stanisław (1704–1793, future voivode of Kyiv) and Józef (1704–1755, Grand podstoli of Lithuania).

Built the masonry church of the Immaculate Conception of the Most Holy Virgin in 1747 — of brick on stone foundations, with a treasury and a sacristy. Endowed it with 800 zlp. (Polish zlotys) for the upkeep of the parish priest, adding ploughland, meadows and a plot. Three altars: the principal one of wood, the side altars painted al fresco. A wooden belfry with three bells.

Józef died childless in 1755 — the Miastkivka key passed in its entirety to his brother Stanisław.

1751 — the foundation deed of Pawłocz (15.XI.1751) names «Józef Lubomirski, Hrabia na Wiśniczu… Miastkowce, Tomaszpolu, Raszkowie, Sawraniu…». This definitively confirms: in 1751 Miastkivka was held by this Józef (†1755), and not by his namesake nephew (1751–1817), who had only just been born that same year

Schematism of 1831 (Szczepaniak, pp. 135–136) Entry on the church of Miastkivka: founder — Prince Józef Lubomirski, 1747.

Szczepaniak J., Diecezja kamieniecka (2019); DAChmO, f. 685, op. 4, file 23

Brother of Józef. Inherited Miastkivka on his childless death (1755). His wife — Ludwika Honorata Pociej h. Waga. They had 7 children, among them Józef Aleksander (1751–1817, castellan of Kyiv) — namesake of his uncle, who continued the founder's tradition (the masonry church at Chechelnyk, 1786).

In the 1760s Stanisław sold off his estates wholesale. In 1766 he sold Krasne with 9 villages to Piaskowski (ESU). The Miastkivka key passed to Antoni Bielski — most probably by purchase, but no deed has been found.

Antoni Bielski herbu Jelita, of Olbrachcice. Court Master of the Crown Hunt (from 1750), starosta of Czerwonogród, Austrian count by grant of Maria Theresa (1778), knight of the Order of the White Eagle (1782). His principal residence — Pieniaki (modern Brody Raion, Lviv Oblast).

His wife — Tekla née Kalinowska, daughter of Ludwik Kalinowski, starosta of Vinnytsia (Bracł. XVII f. 1992). It was this marriage that linked the Galician magnate with the Vinnytsia circle — the landowners of the Bracław region. Through his starosta father-in-law Bielski made his way into the region where, a few years later, he would acquire Miastkivka.

Boniecki (Herbarz Polski, T. 1, pp. 254–255) gives the full genealogy of the Bielski h. Jelita of Olbrachcice: the family originated from Olbrachcice and Lebiońówka (Gr. Lwows. 1753–1762). Antoni had no sons — «nie pozostawił męskiego potomstwa» (Boniecki, T. 1, p. 236). Only daughters: Aniela (× Miączyński), Franciszka (× Ignacy Stempkowski), Julianna (× Dzieduszycki).

Marczyński (1823) places him in the chain of owners: «należała dawniey do Xiążąt Lubomirskich i Bielskich». The Schematism of 1831: co-founder of the restoration of the church (1785) together with Mikołaj Jaroszyński. Endowed 1,600 zlotys for two vicars «na dobrach kolatorskich» — which confirms his status as collator (patron) of the estate.

How Miastkivka passed from the Lubomirskis to Bielski — remains unknown. No deed of purchase/sale has been found. He died 28.II.1789 at Pieniaki, without sons — within two years Miastkivka is already in the hands of Jaroszyński. Probably — by purchase from his daughter-heirs or by an earlier agreement (Jaroszyński had already been co-founder in 1785).

The first documentarily confirmed sole owner of Miastkivka after the Lubomirskis. In 1791 the Land Register (Lwów) records him as sole owner (CDIAL, f. 166, op. 13, file 360, 6 fols., in Latin).

Deputy to the Great Sejm (1790) from Bracław Voivodeship — first on the list of the Bracław deputies (VL T.9). Knight of the Order of the White Eagle (1792). Cup-Bearer of Bracław.

In 1791 the constitution «Sejmiki» included Miastkivka as one of the 8 parishes of Bracław County — alongside Bracław, Tulchyn, Raszków and Balta.

Boniecki (Herbarz Polski, T. 8, pp. 269–270) gives the full genealogy of the Jaroszyńskis. The father — Zachariasz Jaroszyński (1700–1774), podstoli of Vinnytsia — of the same Vinnytsia circle as Bielski's father-in-law (Kalinowski, starosta of Vinnytsia). The wife — Marianna Kordysz (DW. 104 f. 724).

Boniecki calls Mikołaj outright «właściciel Miastkówki» — «owner of Miastkivka».

Died at Miastkivka on 2 October 1805.

Boniecki, Herbarz Polski, T. 8, pp. 277–278 Genealogy of the Jaroszyńskis. Mikołaj — «właściciel Miastkówki». Jan's children are born at Miastkivka (1836, 1841).

Boniecki A. Herbarz Polski. T. 8. Warszawa, 1905

Son of Mikołaj. According to Marczyński (1823): 1,130 male souls in Miastkivka itself (~2,260 inhabitants) plus 5 attached settlements — Bolhany, Khrystysche, Szarapanówka, Wysoka Grobla, Żydówka.

Children were born at Miastkivka: Witold (1836), Zygmunt (1841) — Miastkivka was not merely an estate but a family seat.

Married three times: Anna Malczewska (divorced), Barszczewska, Julia Tyzenhauz.

Boniecki, T. 8, p. 270 Jan — «właściciel Miastkówki, Stawek i Haraczkówki, marszałek olgopolski».

Boniecki A. Herbarz Polski. T. 8. Warszawa, 1905

Jan died in 1842. According to the Polish armorials (Boniecki), four sons divided their father's estates — and none of them is recorded there directly as «owner of Miastkivka»: Konstanty received Szarapanówka, Witold — Horiachkivka, Zygmunt — Stawki. Hence the earlier hypothesis that Miastkivka went to the eldest, Konstanty.

Russian archival files close this gap. DAKhmO f. 241 (inventories of the Bibikov reform, 1845–1851) record the whole estate as the property of the «heirs of the landowner Jan (Ivan) Jaroszyński» — nine objects: the town of Miastkivka, the hamlet of Marianivka, the New and Old Miastkivka folwarks, Żydówka, Wysoka Grobla, New and Old Horiachkivka, Stawki.

A specific name is given by DAVO f. 468 op. 1 file 364: «Case on the induction into possession of the Miastkivka estate of the landowner Henryk Jaroszyński», 1856–1860 — a judicial induction into possession of the Miastkivka estate specifically. Thus after Jan the estate passed legally to Henryk Jaroszyński — the first owner of Miastkivka named by name after his father (Jan's heir; probably the very «fourth son» not named in the armorial — this requires verification against the genealogy in the file itself).
In 1849 Epsztein records Waleria Jaroszyńska (Konstanty's wife, née Budzyńska) with ~2,991 souls.

After 1863 — the January Uprising. The Jaroszyński estates, comprising three keys (Novokostiantyniv, Tyvriv, Miastkivka), passed to count Kochubey. For the Novokostiantyniv key (9,171 desiatinas) SG states outright: «z rozporządzenia rządu przymusową sprzedażą» — by order of the government, after 1863. For Miastkivka SG notes only «dawniej Jaroszyńskich», without details of the mechanism. Zygmunt (b. at Miastkivka 1841) emigrated to Galicia.

After the January Uprising (1863) the Jaroszyński estates, comprising three keys, passed to count Kochubey. For the Novokostiantyniv key (9,171 desiatinas) SG states outright: «z rozporządzenia rządu przymusową sprzedażą» — forced sale by order of the government. For Miastkivka SG notes only «dawniej Jaroszyńskich», without details of the mechanism.

SG (1885) and Sietsinskyi (1901) still name «Kochubey» as owner. However, Huldman (1898) already records Tereshchenko — so the transfer took place somewhere between 1885 and 1898.

The estate was purchased by her father — the entrepreneur Fedor Tereshchenko (ESU: «In the 2nd half of the 19th c. M. was bought by the entrepreneur F. Tereshchenko»; local tradition knew him as «F.A. Tereshchenko»). By the time of Huldman's record (1898) the owner is already the daughter — Natalia Fedorovna (Orthodox, noblewoman of Kyiv Governorate, residing: Kyiv, Aleksiivska St., No. 3). The estate: Miastkivka with the folwark of Mordyt, the village of Marianivka, the village of Lysohirka. A total of 3,550 desiatinas (arable 2,618, forest 726½, homestead 80½). Manager — Semen Feofanovych Khyzhynskyi.

SG (1885) and Sietsinskyi (1901) write «Kochubey», but Huldman (1898) already records Tereshchenko. Sietsinskyi worked with parish documents, Huldman — with official land registers.

Huldman, Landed Estates (1898), p. 224 Miastkivka — Tereshchenko N.F., 3,550 desiatinas.

ESU: «the last owner — the landowner N. Uvarova (Tereshchenko)». The double surname points to a marriage of a Tereshchenko into the Uvarov family.

According to genealogical sources (Geni.com, Rodovid), Natalia Fedorovna Tereshchenko (b. 1890) in 1910 married Sergei Sergeevich Uvarov, marshal of the nobility of Berdychiv County. If this is the same person — local tradition, which knew both «Tereshchenkos» and «Uvarovs», — was right: this is one family through marriage.

Status: hypothesis. A primary source (marriage act, noble register, deed to the estate) has not been found. Verification required.
