I am looking for any knowledge on Kowalski's from Oscislowo, Sulerzyz Parish, Poland. My GGrandfather Adam b.1883. arrived in Canada 1905. His parents Jan Kowalski and Paulina nee Niepytalski. There is no death record of them in this parish although all children where born in this parish. Three siblings stayed in Poland Julianna b.1886 d.1962 in Oscislowo. Tekla b.1900 d.1990 in Oscislowo married name Zimnowodska and Stanislaw b.1897 Oscislowo. I am looking for any descendants of these children or any knowledge on the death records of Jan and Paulina or Stanislaw.
