All about renesmee

"You nicknamed my daughter after the Loch Ness Monster!?"
―Bella Swan to Jacob Black on Renesmee's nickname "Nessie".[src]
Renesmee Carlie Cullen (pronounced Ruh-NEZ-may) (born on September 10, 2006), conceived and carried by Bella Swan, is a half vampire/half human hybrid, and a member of the Olympic Coven. She is the imprintee of Jacob Black, and the daughter of Edward and Bella Cullen. Renesmee's paternal grandparents are Edward and Elizabeth Masen. She is the granddaughter of Charlie Swan and Renee Dwyer, as well as the adoptive granddaughter of Carlisle and Esme Cullen. She is the niece of Alice and Emmett Cullen and Rosalie and Jasper Hale.

Renesmee is considered to be Edward and Bella's "miracle", because of what it took to keep her and her mother alive through the pregnancy. Renesmee also has the special power to show people what she is thinking by touching them.

In the beginning, Bella despises Jacob for giving her daughter the nickname "Nessie". After Jacob Black imprints on Renesmee, Irina, a vampire from the Denali Coven, sees Renesmee and believes she is an "immortal child", a human child who had been bitten by a vampire. She informs the Volturi, as immortal children are not permitted to live. Intent on killing Renesmee and all the Cullens, the Volturi travel to Forks. However, the Cullen family members gather witnesses from around the world to prove that Renesmee is not an immortal child. Alice brings another half-breed, Nahuel, who explains that half-breeds pose no danger to the vampires. Convinced that Renesmee is not a threat, the Volturi leave, and Renesmee and her family are left in peace.



Her name is Renesmee. Like Renée and Esme put together."
―Bella Cullen[src]
"Jake says you call her Nessie?
No we don't. We call her Renesmee."
―Charlie Swan and Bella Cullen[src]
Renesmee's name derives from an amalgamation of the names of Bella's mother, Renée, and her mother-in-law, Esme. Her middle name, Carlie, is a portmanteau of Bella's father-in-law, Carlisle, and Charlie, Bella's biological father. Her full name is Renesmee Carlie Cullen. Jacob Black gives her the nickname "Nessie" because he says her full name is a "mouthful," and due to the fact that he believes she is a monster for almost killing Bella. At first, Bella refuses to use this nickname because of the obvious allusion to the Loch-Ness Monster, but eventually warms to this name along with everyone else by the end of the story. This nickname, in addition to Jacob's imprinting upon Renesmee, made newborn Bella furious enough to attempt to attack Jacob, lunging for his throat. Luckily for Jacob, and to Renesmee's relief (as she later tells Bella), Seth Clearwater, Jacob's friend and right hand wolf, jumped in the way, breaking his shoulder and collar bone in the process (which Bella quickly apologizes for after calming down).
