Jacob and Anna Wroblewski attended the Western Electric employee excursion and picnic with their daughter, Mary. Anna was several months pregnant, and the Wroblewskis' two youngest daughters, Rosie and Pauline, were left at home. Jacob had worked at the Hawthorne Works for nearly seven years.
Anna survived the Eastland Disaster, apparently uninjured, but lost her husband Jacob and oldest daughter Mary. After the death of Jacob, the family's only income was $3 a week board paid by Anna's sister. The emergency relief and benefit paid by the Western Electric Company was $596. The emergency relief by the Red Cross was $2,849 which was placed in trust, to be paid $30 a month.
Four months after the tragedy, a boy was born to Anna. He was named Jacob; he died but a few days later.
