Anne Carroll Moore was born on July 12, 1871, in Limerick, Maine. She was the daughter of Luther Sanborn Moore and Sarah Hidden Barker. Anne (she was christened Annie) was preceded by two sisters, who had died, and by seven brothers. As favorite in the family, she had a special closeness to her father, a lawyer, who had served as president of the state senate. Luther Moore died on January 12, 1892, and his wife died two days later, which ended Moore's interest in the law.
