Even when they are centuries old, royal paternity disputes are fascinating. DNA studies of the recently discovered bones of Richard III suggest that the entire Plantagenet dynasty may have been illegitimate.
During the 19th century hundreds of imposters claimed to be the Dauphin of France, the son of Louis XVI of France and Marie Antoinette who had allegedly escaped from his Republican captors. A DNA test in 2000 proved that this was false: he had died in captivity as a child.
