Hader Family 1. Open

my grandmother Walerja Hader was born in 1902, sisters Marya 1888, Agnieszka 1892, brothers Antoni 1898 and Wladyk 1900.  Their father was Antoni born abt 1865 and his wife I believe was Katarzyna.  I am looking for more information on what my great grandmothers name was and date of birth and possibly both sets of great great grandparents & parents names.  I am appreciative for any help I may receive.  Wishing everyone a better 2021 than 2020.
