I wanted to post the information I had on my Sepetowski connection in case someone else was looking for this family line.
Jan SEPETOWSKI and Ewa KURKUS had a daughter named Malgorzata. She was born c.1852. She married my great-great grandpa Jan JACKOWSKI sometime around 1867. She had the following children: Adam (c.3/1867-12/2/1867), Franciszek (c.1869-?), Karolina (11/4/1874-?), Stanislawa (10/15/1877-?), and boy Jackowski (stillborn 5/21/1880). They lived in Dobrska when Adam was born. Malgorzata then died 12/26/1880 in Borzewo Kmiece, Poland and was buried in Gralewo. Jan SEPETOWSKI died sometime before 1880, he is listed as deceased on her death record. My relation is through Jan JACKOWSKI and his 2nd wife Katarzyna BUDZINSKA.
