The mitochondrial DNA match was a huge piece of the puzzle, but just to make absolutely sure they had the right guy, the researchers covered their historical bases. Mitochondrial DNA could have been shared by other relatives of Richard who were alive at the same time he was. To eliminate the possibility of a contemporaneous body double with similar genetics, Schürer combed through the history books and genealogies tracking down any relatives of Richard’s who were around the same age and who might have been at the Battle of Bosworth. Of the 82 candidates, most were already dead by the time of the battle or died at a later date. Only one, Robert Eure, was unaccounted for, and records show that he was a Knight of the Order of St. John of Jerusalem, so he was likely overseas when the battle of Bosworth took place.
