Siekluccy family

Some sources indicate that in Eišiškės and surrounding areas lived as many as 16 representatives of noble families, including Siekluccy family prevailing in the estate in Gornostajiškės. The last owner of the property was arrested in 1939 and probably executed in Lida. In Eišiškės still exist orally transmitted tales of the nobility and prudence of Józef Sieklucki, social activist and the member of the Border Landowners Association.

Among the vivid figures of this family, Barbara Kostrowicka of Siekluccy should be mentioned as the founder of the Church of Saint Spirit in Vilnius. Another member of the family, Wincenty Sieklucki, supported the January Uprising, which caused in consequence the imposition of sequestration of the property in Gornostajiškės.

At the cemetery near the church in Eišiškės exist several graves of members of Sekluccy family, including Marya Sieklucka of Jundziłłowie, Anna Sieklucka, Jan Sieklucki, Józef Sieklucki, Łucjan Sieklucki and Wincenty Sieklucki – the chamberlain of the Lida district.
