Miscellaneous facts about Jasper, courtesy of the Twilight Lexicon
Jasper’s last name is Whitlock. He was human in Texas during the Civil War (his story will be told in detail in book three), so only Carlisle has been a vampire longer. He was twenty when he became a vampire (he was changed by a vampire named Maria). Alice’s nickname for him is "Jazz." He is 6′3" tall.
Rosalie is all about show; Emmett loves to make her happy–hence, lots of elaborate weddings. (When her history is public record, I think it will be more clear why she is the way she is.) Alice and Jasper aren’t into show, but they have the deeper relationship. They are married, but once was enough for them. Esme and Carlisle are also married, again, just the one time.
Emmett and Jasper have a hard time passing for younger than eighteen, but with their perfect credentials (birth certificates, driver’s licenses, etc.) people tend to accept whatever story they tell.
Jasper is very scholarly.
And from Wikipedia
Jasper Hale (born Jasper Whitlock) is the adopted son of Carlisle and Esme, adoptive brother of Edward, Emmett, and Rosalie, and husband of Alice. He was born in Texas and joined the Confederate States Army in 1861 to serve in the Civil War. Due to his extremely charismatic personality, he ascended through the ranks quickly. Jasper was turned into a vampire in 1863 by a vampire named Maria when he was 20 years old. As a vampire, he gained the ability to manipulate the emotions of those around him. Recognizing his high rank in the army, Maria decided to change him into a vampire to help her claim territory in Monterrey. Jasper's responsibility was to train young vampires and then kill them when they were no longer useful (about a year after their transformation- when their strength began to fade). After about a century of this, he grew weary of the lifestyle and joined an old friend, Peter, and his mate Charlotte. Jasper left the two eventually, not wanting to feed on humans because he could feel his prey's emotions as they died. Alice, foreseeing that they would be together, met him in a half-empty diner in Philadelphia, and together they sought out the Cullen family. Due to his past, where he was able to feed on humans whenever he chose, Jasper lacks strong self-control. However, in Eclipse it is suggested that the "vegetarian" lifestyle is not Jasper's first choice and that this also affects his self-control. He is described as tall with honey blond hair, and is muscular but lean. His body is covered with crescent-shaped scars, after the many years of fighting and training newborn vampires.
In Twilight, Jasper accompanies Alice and Bella when they are hiding from James. He uses his ability to calm Bella when she is stressed or afraid. In New Moon, he attacks Bella after she gets a paper cut, prompting the Cullen family to leave Forks to protect Bella. In Eclipse, Jasper teaches the werewolves and vampires fighting techniques to defend themselves against newborn vampires. In Breaking Dawn, Jasper leaves with Alice to find a vampire-human hybrid, and returns with her to defend Renesmee from the Volturi.

Personal history: Jasper served as a Major in the Confederate army during the Civil War. The vampire family that changed him in 1863 (TL) was very different from the Cullens in their dietary habits –they fed off humans. (PC2) Jasper became depressed over his way of life and sought something better. His search led him to Alice in 1948 (TL), which in turn led him to Carlisle in 1950. (TW14) (TL)
Jasper has the most difficult time with the lifestyle set by the Cullen family. He avoids contact with humans, as he is more tempted than the others to drink from them. Going to school is a difficult task, but he does it for Alice. (PC2)
He would do anything for Alice, as she is his whole life. Even though he treats the other members of his family with respect, he isn’t bound to them the way he is to Alice. (PC2)
Jasper uses the last name of Hale because he and Rosalie look so much alike and people assume them to be twins. The vampires tend to go with whatever the humans are willing to believe. Rosalie insists on using Hale as a last name, and therefore, Jasper took it as his, too.
