According to Wrestleview reader Randy Johnson:

Jonathan and Joshua Fatu, the sons of Rikishi (and nephews of Umaga), were working under the Tag Team name “The Samoan Soldiers” on the Georgia Independent scene in January of this year. Jonathan Solofa Fatu & Joshua Samuel Fatu (full names) are twins both born August 22, 1985. Jonathan Fatu received a WWE developmental contract, and began working in FCW under the name “John Fatu”. His ring name has since been changed to Jimmy Uso. Jimmy Uso is NOT Pate Fifita (son of Haku) or Reon Mahima as many suspected, it’s John Fatu.
