Irina Kozhina of Kashin

Righteous Irina Kozhina of Kashin († c. 1419-1420) was the wife of the righteous Vasily of Kashin and the mother of Venerable Makarios of Kalyazin. She has been venerated as a local saint in the Tver diocese since the twentieth century and is entered in the Synaxis of All Saints Who Shone Forth in the Russian Land.

Her background is unknown, but the data about her family suggest that she was from a notable family of Tver. Dosithei Toporkov, in the Joseph-⁠Volokolamsk Paterikon, calls Makarios of Kalyazin "a kinsman of the great Tver boyars." The fate of her children and grandchildren, devoted to the service of church and state, suggests that she was a literate woman. She and her husband had four children: Matthew (Venerable Makarios), Alexander, Gregory and Xenia. Gregory was tonsured a monk and in 1461 was consecrated bishop of Tver (Gennady Kozhin). Xenia's son was Venerable Paisius of Uglich, her grandson, and another grandson, Vasily Alexandrovich Kozhin, was a boyar's son of Grand Prince Mikhail Borisovich of Tver. Her death is dated from the Life of Venerable Makarios: she and her husband died a year after their son's wedding. Makarios was born probably in November 1401 or early 1402 and was widowed at twenty, in 1421, after three years of marriage, so the marriage was in 1418.

Irina was venerated together with her husband. At the beginning of the twentieth century Archbishop Demetrius Sambikin of Tver entered her name and that of the righteous Vasily in the list of locally venerated saints of the Tver diocese. They do not appear in the "Calendar of Russian Saints" of Archbishop Sergius Spassky (1903). Their inclusion in the Synaxis of All Saints Who Shone Forth in the Russian Land, established in the second half of the 1970s in preparing the Menaia, is regarded as a general canonization. She is commemorated on the second Sunday after Pentecost.
