John died the next year, in 1975.
John was married twice. He married Ewa Puzo and had a daughter, Maria Dul. (At age 29, Maria began corresponding with Jan Chawa, who moved from Germany to Australia in 1950. On Nov. 6, 1966, Maria Dul moved to Australia, married Jan two months later, and began a family there.) Ewa Puzo died in 1946 when Maria was only 8.
John married again. He and Aniela (Nellie, last name unknown) had two daughters, Teresa Dul Marut and Janina (Jane) Dul Marut. By happenstance, both daughters married husbands named Marut, though they’re not related. According to Krystyna Chawa, Aniela died in 2001 at the home of her daughter, Teresa Dul Marut, in Gwozdziec, although Rose Krzys Dul (mistakenly) said Aniela was buried years before in St. Michael’s Cemetery in South Hackensack, NJ.
John Dul was Joseph Lasica‘s second cousin.
