Third child and eldest daughter of the future George V and Mary of Teck, Mary's title "Princess Royal" was given to her in 1932 by her father after he'd become King.
The couple had two sons. Rumors were that Mary was forced into the marriage but her son reported that their marriage was happy.
Mary played a part as controller commandant during World War II of what became the Women's Royal Army Corps after the war. She was named an honorary general in the British Army.
Mary's life spanned the reigns of six British rulers, from her great-grandmother Queen Victoria through her niece Queen Elizabeth II.
