My wife's grandfather Waclaw Bartold had a sister who's first name was probably Wiktoria. She was married to Osowski or Ostrowski. They came to USA after 1900 and settled in Chicago. They were from Ciechanow area in Poland. Waclaw and his wife Genowefa tried to joint his sister's family in 1913 but was turned back from Ellis Island due to bad healh.
Waclaw was in contact with his sister untill the 1940's.
Osowskis or Ostrowskis owned textile store in Chicago and had a two daughters.
