Hello-
My grandfather (Jacob Walczak)married Anna Kaleta (his first wife) in Chicago IL in 1911. She indicated her parents were named Stanislaw, and Zofia (nee Sobieraj). She came from Kazimierz, Kielce (Russian Poland). Jacob and Anna had 2 sons--Bronislaw (born in 1912) and Benjamin (or Boleslaw) born in 1915. Their second son died in 1915 (4 months old)and I have not been able to find Bronislaw in any records.
Anna Kaleta Walczak died in 1915--3 months after her 2nd son died. She was 22 years old.
