She was born Florence Louisa Charlesworth in Limpsfield, Surrey, England, the daughter of the local Anglican rector. One of three girls, she was a sister to Maud Ballington Booth, the Salvation Army leader and co-founder of the Volunteers of America. When Florence was seven years old, the family moved to Limehouse in the London Borough of Tower Hamlets. In 1881, Florence Charlesworth married the Rev. Charles W. Barclay and honeymooned in the Holy Land where in Shechem they reportedly discovered Jacob's Well, the place where, according to the Gospel of John, Jesus met the woman of Samaria (John 4-5). Florence Barclay and her husband settled in Hertford Heath, in Hertfordshire where she fulfilled the duties of a rector's wife. The mother of eight children, in her early forties health problems left her bedridden for a time and she passed the hours by writing what became her first romance novel titled "The Wheels of Time." Her next novel, The Rosary, a story of undying love, was published in 1909 and its success would eventually see the book translated into eight languages and made into five motion pictures, also in several different languages. According to the New York Times, the novel was the No.1 bestselling novel of 1910 in the United States. The enduring popularity of the book was such that more than twenty-five years later, Sunday Circle magazine serialized the story and in 1926 the prominent French playwright Alexandre Bisson adapted the book as a three-act play for the Parisian stage. Florence Barclay wrote eleven books in all, including a work of non-fiction. Her 1910 novel, "The Mistress of Shenstone," was made into a 1921 silent film of the same title. Her short story, Under the Mulberry Tree appeared in the special May 11, 1911 issue called "The Spring Romance Number" of the Ladies Home Journal. Florence Barclay died in 1921 at the age of fifty-eight. "The Life of Florence Barclay; a study in personality" was published that year by G. P. Putnam's Sons without the author's name, labeled only as "by one of Her Daughters."
