Yep, the middle name was spelled Aaron not Aron.
I think it was spelled Aaron though!
I just checked wikipedia and came up with this...interesting.
The correct spelling of his middle name has long been a matter of debate. The physician who delivered him wrote "Elvis Aaron Presley" in his ledger.[343] The state-issued birth certificate reads "Elvis Aron Presley". The name was chosen after the Presleys' friend and fellow congregation member Aaron Kennedy, though a single-A spelling was probably intended by Presley's parents in order to parallel the middle name of Presley's stillborn brother, Jesse Garon.[135] It reads Aron on most official documents produced during his lifetime, including his high school diploma, RCA record contract, and marriage license, and this was generally taken to be the proper spelling.[344] In 1966, Presley expressed the desire to his father that the more traditional biblical rendering, Aaron, be used henceforth, "especially on legal documents."[343] Five years later, the Jaycees citation honoring him as one of the country's Outstanding Young Men used Aaron. Late in his life, he sought to officially change the spelling to Aaron and discovered that state records already listed it that way. Knowing his wishes for his middle name, Aaron is the spelling his father chose for Presley's tombstone, and it is the spelling his estate has designated as official.
OK next question.
