Characters from fiction also seem to influence naming. After the name Kayla was used for a character on the American soap opera "Days of Our Lives", the name's popularity increased greatly. The name Tammy, and the related Tamara became popular after the movie "Tammy and the Bachelor" came out in 1957. Some names were established or spread by being used in literature. Notable examples include Pamela, invented by Sir Philip Sidney for a pivotal character in his epic prose work, "The Countess of Pembroke's Arcadia"; Jessica, created by William Shakespeare in his play "The Merchant of Venice"; Vanessa, created by Jonathan Swift; Fiona, a character from James Macpherson's spurious cycle of Ossian poems; Wendy, an obscure name popularised by J. M. Barrie in his play "Peter Pan, or The Boy Who Wouldn't Grow Up"; and Madison, a character from the movie "Splash". Lara and Larissa were rare in America before the appearance of "Doctor Zhivago," and have become fairly common since.
