Annia Aurelia Galeria Lucilla was the daughter of the Roman emperor Marcus Aurelius and Roman empress (due to marriage with Lucius Verus). She was executed by the Roman emperor Commodus.
This is a beautiful and elegant name! In 1844 an anonymous lady author, who had also written "Happy Hours With Mamma", published a book called " '"Lucilla Hartley: or, Discipline illustrated; a narrative founded on occurrences in real life" - it was described as "A pleasing little story, intermingled with various sorts of information, as conveyed by some young ladies to their teacher. The characters are fictitious, but many of the incidents and anecdotes real."
