Francesca Latimer was the daughter of Captain Latimer and sister of Digby Latimer, who called her "Frannie". The children and their father lived in London. Francesca watched her governess, "Miss Montague", die in the last seconds of Christmas Eve, 1892, from massive internal injuries stemming from a fall from cloud level.
She and Digby's prior governess died a year earlier from drowning in an icy pond; that governess began to appear in Francesca's dreams in late 1892, chastising Francesca and stating that she was coming out of the frozen pond on Christmas Eve to get her. Francesca's mother died some time earlier. (TV: The Snowmen)
