Ottilie is a female given name stemming from the medieval German boy's name Otto and meaning "riches", "wealth" or "prosperity". It has never become very popular in modern culture and has remained very low on popularity rankings only reaching its peak in 1880 when it reached almost 600th position in the US. Ottilie is a much more common first name in German-speaking countries.
Ottilie was the name given to the female protagonist in John Wyndham's science fiction story "Random Quest" later made into a film "Quest for Love", starring Joan Collins as Ottilie, Tom Bell, Denholm Elliott and Laurence Naismith. The story is about a scientist, Colin Trafford, who crosses into a parallel world after a scientific demonstration goes wrong. He finds himself married to Ottilie Harshom, falls in love with her, and then desperately looks for her when he returns to his own world - the "quest" of the title.
