My initial instinct was to dismiss it as a coincidence as there are many people who have doppelgängers.  However, the Jews do always boast about how pure and related they are to each other I wouldn't doubt that they are cousins and they are about 12 years apart according to wiki.  One of the things that you find going down the rabbit hole is how obsessed the elite are with bloodlines--Jews more so than the rest of us plebs
