Donna Troy was created in 1965.

Donna Atwood went by The Sweetheart of the Ice.

You may be referring to Donna Troy, who is an adopted Amazon ward of the real Amazon, Princess Diana ( not of Windsor!)- Wonder Woman of Themyscira Island. Donna Troy means ( mixture of Italian and Greek) Lady of Troy. Wonder Woman is steeped in Greco-Roman mythology, by the way. Her speed comes from Mercury ( no, not the Flash character).

Her name was Dorothy Hinckley. She was only 21 when she had Donna and gave her up for adoption because she was dying of cancer.

Marcia Long, Terry Long's ex-wife disliked Donna because of her age and unconventional lifestyle. She was rude and sarcastic, and believed she was an "inappropriate" role model for her daughter, Jennifer. When Terry, Jennifer, and Donna's son Robert, died in a car accident, she became more hateful toward the superhero community.
