Fred and George Weasley were identical and mischievous twin wizards born on 1 April, 1978 to Arthur Weasley and Molly Weasley (née Prewett). Brilliant pranksters, they co-founded and ran the joke shop Weasleys' Wizard Wheezes and were members of both Dumbledore's Army and the Order of the Phoenix. See their individual articles for more information:James Phelps and Oliver Phelps respectively. Oliver is actually the older twin, but Fred is older than George. The difference between the Phelps twins is that Oliver has a mole on the right side of his neck, while James does not.
