In September 1920, Jan Skrok and Agnieszka Kapuścińska Skrok returned to Poland with their two oldest children Helena and Czesław. The United Kingdom Incoming Passenger Lists show the family arrived from the port of New York on the ship Kaiserin Auguste Victoria of the Cunard Steamship Company to Liverpool, England, on 20 September 1920. Their destination was the Free City of Danzig, currently Gdansk, Poland.
The following September, Andrzej Kwiatek and Maryanna Kasprzyk Skrok Kwiatek returned to Poland with their children Julia, Aniela, Leon, and a new baby, Zofia Kwiatek. (Was Zofia Maryanna‘s daughter, or Julia‘s baby? Maryanna was born in 1871. Her first child with Wincenty Skrok, Stanisław, was born in 1889. She was older than her second husband, and had three children with him. Their son Leon was born in 1915. In 1921, Maryanna was 50 years old and Julia was 17. I imagine either situation would have been difficult for the family.) They left from the port of Montréal, Québec, Canada, on the ship Megantic of the White Star Dominion Line. They arrived in Liverpool, England, on 18 September 1921 in transit to Antwerp, Belgium.
Update February 2022. A baby named Zofia Kasprowicz was born in Buffalo, Erie, New York, on 7 January 1921, but was this a child of John Kasprowicz and Julianna Kwiatek? No baby named Zofia Kwiatek was identified in New York or Pennsylvania records.
