Kawulok, Michał
?-?piper (&c.) mentioned by name
Brother of Jan "uod Wojtosza"; Though shown playing the Gajdy in a photo, together with his brother (violin), Katarzyna and Maciej Szymonowiczowie refer to him only once (and only casually, at that), in their paragraph dedicated to Jan, thus failing to provide us with even essential biographical information.
Instrument: Gajdy śląskie
Szymonowiczowie, Katarzyna & Maciej: Gajdosze (album). Żywiec, 2014, p.14*, 158.
