Katinka, Sari, Ella, Mici, Terka, Liza and Klara were the names of the seven sisters in the lost silent film The Seven Sisters (1915), which was based on a Hungarian play.
A 1916 advertisement for the movie, which was a vehicle for silent film actress Marguerite Clark, offered the following summary:
The story is as simple and as sweet and dainty as Little Marguerite herself. She is the fourth of a family of seven sisters. Under an old Hungarian marriage law she must not marry until the elder sisters have gone off. How she and her lover clear the way with the aid of that young man’s marriageable friends affords scope for some delightful comedy amid the quaintest and most beautiful old-world surroundings ever portrayed.
The names Katinka, Sari, Ella, Mici, Terka, Liza and Klara are Hungarian versions (or diminutives of Hungarian versions) of the names Katherine, Sarah, Eleanor (or some other El- or -ella name), Mitzi, Theresa, Elizabeth and Clara.
