Jacquelyn Marie Gray, 31, of Center City, a lawyer, died of breast cancer Feb. 11 at the Hospital of the University of Pennsylvania.

Since 2005, Ms. Gray had been an associate with Ballard Spahr in Philadelphia. Her practice focused on pension plans, compensation, and benefits at corporations and tax-exempt institutions.

In 2008, the Philadelphia Volunteers for the Indigent Program recognized her pro bono work on tax returns for low-income individuals.

Though she fought cancer for eight years, she lived life to the fullest and was at work until a week before her death, said a sister, Elizabeth Hall.

Ms. Gray sang in the chorus of the Sweet Adelines, Greater Harrisburg Chapter, and was a member of its Sugartown quartet. She rowed with the Philadelphia Dragon Boat breast cancer survivors' team and competed in a race in Montreal two years ago.

A native of Fostoria, Ohio, Ms. Gray earned a bachelor's degree from the College of Wooster in Ohio and a law degree from Georgetown University. She was an attorney for the Pension Benefit Guaranty Corp. in Washington before moving to Philadelphia.

In addition to her sister, Ms. Gray is survived by her parents, Robert and Sandra; another sister, Carol Tennant; her grandfather George A. Gray; a nephew; a niece, and her partner of four years, Bill Rieger.

The funeral was private. To honor her memory Feb. 21, eight friends and relatives ran as Team Jacque in the Donna Foundation's National Marathon to Finish Breast Cancer in Jacksonville, Fla. The event benefited cancer research at the Mayo Clinic.
