Who is Elizabeth Swann:

Elizabeth Turner (née Swann) is a fictional character in the Pirates of the Caribbean film series. She appears in The Curse of the Black Pearl (2003) and three of its sequels, Dead Man's Chest (2006), At World's End (2007) and Dead Men Tell No Tales (2017).She is portrayed by Keira Knightley (and as a child by Lucinda Dryzek in the prologue of The Curse of the Black Pearl). She is known to use the alias "Elizabeth Turner", but this later becomes her married name when she weds Will Turner.

Elizabeth is the only child to Weatherby Swann, the love interest (later wife) to Will Turner, mother to Henry Turner and daughter-in-law to William “Bootstrap Bill” Turner.

Elizabeth is a spirited, intelligent, and independent-minded character whose beauty attracted Will Turner, James Norrington, Sao Feng, and Captain Jack Sparrow. Only Will Turner's affections were reciprocated, although she struggled with a subtle attraction and kiss with Sparrow, and a compassionate friendship with Norrington. Throughout the three films, she transforms from a young girl to a proper lady and finally into a courageous pirate. Elizabeth has always been fascinated by piracy, but she is often revolted by pirates' aggressive, wild nature. Even after becoming a pirate, Elizabeth retains her refined ways, as well as her loyalty and compassion for loved ones (including Will Turner, her father, and later, Jack Sparrow and James Norrington).
