Shirley Temple's first marriage, according to Amomama, was to the actor John Agar, who married the former child star when he was 24 and she was 17. Though their marriage was brief, it produced a child: Linda Susan Agar was born to the couple in 1948. The daughter, who apparently went by Susan, would effectively spend the entirety of her life outside of the public eye, as she appears to only emerge from time to time to give interviews about her mother, such as the one she gave to Closer Weekly in 2015. 

"As a mother, she was devoted and generous, although she could be a little bit stern if we didn't behave," she said at the time. "But family was a really, really important part of her life. She was all about her children and her husband."

"She was a wonderful cook," Agar added. "She loved to invite people over. She would say, 'Come by my house and I'll make you leg of lamb.' She made a beautiful lamb and was famous for her mashed potatoes!"

Similarly, Temple's second-oldest child, Charles Black Jr., who was born from his mother's second marriage (to businessman Charles A. Black, via Britannica), also seems to have preferred a life of quiet anonymity. It appears as if he is, or was, a real estate agent, per his profile on Realtor.com. Like his half-sister, Black praised his mother in 2015: "She had good energy and a wonderful sense of humor. She was extraordinary," he said.
