Hajsyn Podolia - died 29 November 1913 Paris) was a Polish landowner, social activist, supporter of the arts and philanthropist.

He was the youngest of four and the only son of Ludwik Sobański (1791-1837) and his wife, Róża, née Łubieńska, daughter of Feliks Lubienski and Tekla Teresa Lubienska.

His father fell foul of the Russian authorities due to his dissident stance and was sentenced to years of exile in Siberia.

[1][2] Feliks' eldest surviving sister, Paulina (b.1824), married Adolf Jełowicki (1809-1891), veteran officer of the November Uprising in Podolia.

[4] Following the death in 1869 of his relative, Eustachy Jełowicki, another November Uprising veteran, Sobański became the legal guardian of his five children.

When in 1862 his colleagues decided at an assembly in Kamieniec Podolski to seek to join the counties of Podolia and Wołyń to Congress Poland, he opposed the idea, but was out voted.

As a result, all the marshals were suspended from office, including Sobański, and were taken on remand to the Peter and Paul Fortress in St. Petersburg.

He ran an architectural competition under its auspices in 1878 to design a parish church for the Mill town of Żyrardów, for which he donated the land.

Among his other philanthropic projects were: Sobański supported financially many social institutions in his homeland as well as in Paris, where there was a substantial Polish diaspora and where he settled for the last dozen years of his life.

[11] His remains were transferred to Obodówka in Podolia, shortly after the outbreak of World War I, but border controls prevented his family from abroad attending the interment.
