Rosemary Roberts, the mother of Supreme Court Chief Justice John Roberts, has died. She was 90. A spokeswoman for the court said Rosemary Roberts died Saturday. Roberts was born Rosemary Podrasky in Johnstown, Pennsylvania, and married John G. Roberts Sr. in 1952, according to an obituary published in The Tribune-Democrat.

She worked in Pennsylvania and New York as a customer service representative for A&P supermarkets and the Bell Telephone Company, according to the obituary.

The family moved around over the years for Roberts Sr.’s job at Bethlehem Steel Corp. and lived in New York, Indiana, Pennsylvania and Maryland. They later moved to Ohio and South Carolina for other business opportunities and for retirement.

Rosemary Roberts participated in local religious and charitable organizations and served as a hospital and library volunteer, the obituary said. She and her husband moved to Maryland in 2001 to be closer to their family.

Their son, John Roberts, was nominated in 2005 by President George W. Bush to be chief justice of the Supreme Court. He replaced the late William Rehnquist.

Rosemary Roberts is survived by four children, six grandchildren and one great-grandchild. Her husband died in 2008 after a long illness.
