Married first to Petar Maravich, second marriage to George Kosanovich.

It was the promise of steady employment that lured Pete Maravich's paternal grandparents, Vajo and Sarah (Radulovich), to western Pennsylvania. They left Dreznica, Lika (later Yugoslavia) and became part of a huge Serbian migration to the United States at the close of the 19th century. 

The Serbs quickly gained a reputation as tough, hard laborers who would accept backbreaking jobs in the copper, gold, coal, and steel industries. It was dangerous work with minimal government safeguards or union protection. Vajo Maravich found steady employment as a locomotive engineer for a mill and started a family. Although Vajo and Sarah could barely speak English, they rented a small house on Sarah Street on the south side of Pittsburgh and had 10 children. They were living the immigrants' dream in a new world full of opportunities, but their life was about to take a tragic turn. 

One evening in 1917, while working the midnight shift, Vajo was killed in a train accident in Clairton, Pennsylvania. More misery struck Sarah and her children in the fall of 1918 when the worldwide flu epidemic spread to the United States. It was the most lethal epidemic in human history, killing an estimated 30 million worldwide and 195,000 Americans in October alone-the deadliest month in U.S. history. By the time the killer flu ran its course more than 550,000 Americans had died, including nine of Sarah's children. The only surviving child was a robust boy named Peter who, by most accounts, had turned three on August 29, 1918.

Somehow Sarah found the strength to overcome her staggering tragedy. She married another steel worker named George Kosanovich, and bore him two children, Sam and Mark. In the early 1920s, the family of five moved 20 miles northwest to Aliquippa, Pennsylvania, one of 13 "River Bottom Communities."
