Article: During 1824–28 Chopin spent his vacations away from Warsaw, at a number of locales.[n 4] In 1824 and 1825, at Szafarnia, he was a guest of Dominik Dziewanowski, the father of a schoolmate. Here for the first time he encountered Polish rural folk music. His letters home from Szafarnia (to which he gave the title "The Szafarnia Courier"), written in a very modern and lively Polish, amused his family with their spoofing of the Warsaw newspapers and demonstrated the youngster's literary gift.

Question: To whom did Frédéric write letters to during his stay in Szafarnia?
his family
