Cpl. Jennifer Marie Parcell, 20, of Bel Air, Md., died Wednesday "while supporting combat operations in Anbar province," the Department of Defense said.
"If you knew her, you loved her. She was a go-getter. She knew what she wanted in life, and she was doing what she had to do to achieve that," Parcell's aunt, Martha Benton of Aberdeen, said.
Parcell joined the Marine Corps in January 2005. Benton said she'd wanted to enlist since attending her brother Joseph's graduation at Parris Island.
Joseph Parcell, 24, enlisted in February 2003, and he is returning from his tour to be with family.
The brother and sister were stationed together in Iraq for about a month before their tours of duty separated them, Benton said.
Math was her forte at Fallston High School in 2004, Benton said. She said Jennifer Parcell always enjoyed the water, including boating and scuba diving. She also liked yoga and music and spending time with family and friends.
Jennifer Parcell was assigned to Combat Logistics Regiment 3, 3rd Marine Logistics Group, III Marine Expeditionary Force, based in Okinawa, Japan.
She had earned six medals, and Benton said Marine Corps officials told the family Jennifer Parcell may be eligible for a Purple Heart.
"We're just going to miss her very, very much," Benton said. "She was always someone you could count on."
The family was notified of her death Wednesday afternoon.
