Frances Ellen Wild (maiden name: Sullivan) was born around 1829 in Boston, Massachusetts, to John and Marian Sullivan. Her father was a merchant, and her mother was a music composer. She probably grew up in Boston, and she married Edward A. Wild on June 12, 1855. They traveled to the Ottoman Empire soon afterward, and her passport application described her as 5 feet, 2 ½ inches tall, with black hair and dark eyes. The couple had no children. They lived in Brookline, Massachusetts, and her husband worked as a physician. By 1860, they owned $7,000 of real estate and $2,000 of personal property.
After the Civil War, her husband worked as a silver miner in Nevada. She remained behind in Massachusetts. Her husband died on August 28, 1891, and by 1900, she was living with her sister in Cambridge, Massachusetts. She moved back to Brookline in the early 1900s, and she employed two nurses and a servant. She died of “old age” in Brookline on October 3, 1923.
