Edward is technically the first to join Carlisle Cullen, Esme is second, Rosalie Third, Emmett Fourth. Alice and Jasper are joint 5th since they both arrived together having waited until the right time to meet them. If you were to count Carlisle as the first instead of Edward then Emmett would be the Fifth member to join the family.
spoiler alert!!!!!!!! Jacob, a couple of minutes after Renesmee was born, if you can count imprinting on a member of the Cullen's family as joining it. And if you can't, then Renesmee.
it was jasper
1948
Jasper
the last person to join the family was Renesmee after being born in breaking dawn.
no, she is going to join the Cullen's coven. Since she has had time to "prepare" before becoming a vampire she has incredible "self-control" as good as Carlisle Cullen's, and he worked to get this self control for many years, and she had it right off.
If you consider Carlisle as being the first, Edward was second.Esme was changed into a vampire right after Edward. Here is the order of transformations...CarlisleEdwardEsmeRosalieEmmettAliceJasper technically Jasper is older than Edward but was last to join the family, he and Alice were not created by carlisle.
SPOILER ALERT!!! DO NOT READ ON IF YOU HAVE NOT READ BREAKING DAWN!!!!!!! Depending upon which book you are at, and the page you are on, the newest vampire may be Bella or Renesmee, if you are in Breaking Dawn. If you are not in Breaking Dawn, the answer would be Alice and Jasper - they joined together.
Renesmee (Bella and Edwards daughter)
yes everyone forgives jasper for that, he is the newest (besides bella) to join the Cullen's family and become a vegetarian vampire, so it was harder for him to control himself.
The Cullen family is often referred to as the Olympic Coven and its members joined in the following order: Carlisle (founder) Edward Esme Rosalie Emmet Alice & Jasper Bella Renesmee
From the "Twilight" series, there is Carlisle Cullen, Esme Cullen, Alice Cullen, Jasper Hale, Rosalie Hale, Emmett Cullen and Edward Cullen(later Bella Cullen and Renesmee Cullen)
