Emmett's last name is Cullen. Jasper's last name is Hale.
You never find out what Emmett's real last name is, so the Cullen's just decided to make it Cullen.
They wanted to stay kind of hidden and conspicuous, so they had Jasper share a last name with Rosalie. Jasper's original last name is Whitlock. Rosalie and Jasper are both pale, tall and extraordinarily beautiful, so they could get away with being twins.
Jasper and Rosalie's last name from the book "Twilight" is Hale. They pretend to be twins and foster children to Esme Cullen.
Jasper's real name is Jasper Lee Whitlock Cullen. He takes on the name Hale so that people will think that he and Rosalie are siblings.
Jaspers middle name is not actually revealed. Whitlock was his last name when he was human. Hale is Rosalie's last name. Rosalie and Jasper are supposed to be twins (because they are both blonde), which is why they do not take on the name Cullen (used by all the others in the family).
Born Jasper Whitlock; changed to Jasper Hale when he joined the Cullens (he took on Rosaile's last name--Hale--to pass them off as twins.

Jasper's last name was Whitlock and Rosalie's was Hale but it got changed to Cullen when they became vampires :D
rose is hale (and Jasper's is hale to the public because there pretending to be brother and sister)but Jasper's name before he became a vampire was WhitlockRosalie and Jasper both go by Hale because Rosalie insisted her last name be Hale, but Jasper and Rose look so much alike that they both go by Hale. Jasper's name before he was a vampire was however Jasper Whitlock.
Jasper's last name was Whitlock and Rosalie's was Hale It helps if you read "Eclipse"
Edward, Emmett, and Alice all have the last name of Cullen. Jasper and Rosalie have the last name of Hale.
Emmet's last name is not whitlock. Jasper and Rosalie's are. and I don't know.
Rosalie and Jasper's last name is Hale because Rosalie was too proud to give up her last name of Hale, and because Rosalie and Jasper look so much alike(almost like brother and sister), Jasper decided to take Rosalie's name. Edit-They're also supposed to be twins and the neice and nephew of Esme. Esme and Carlisle adopted them when their parents 'died'. Jasper was called Jasper Whitlock when he was human.
Jasper and Rosalie's last name from the book "Twilight" is Hale. They pretend to be twins and foster children to Esme Cullen.

The members of the Cullen "family" are trying to keep up the pretense that they are actually related. Edward, Alice, and Emmett took on the name Cullen when they were "adopted" by Carlisle and Esme; but it would be creepy for Alice and Jasper (and Rosalie and Emmett) to have the same last name, since they're together romantically. So Rosalie kept her original last name and they pretend that Jasper is her twin brother, hence his last name.
When Rosalie was changed, the cullens played up that Rosalie and Jasper looked so alike and so named her Hale. Rosalie Hale. I'm really not sure wat her name was in her human years sorry.
