Hamlet, the lead character in one Shakespeare's best plays, was a Danish prince - but he may actually have been Irish, according to a piece in the Review of English Studies. Though this be madness, yet there is method in 't.
Rather than being based on Amlethus, from the 13th century "History of the Danes," or even farther back in Amlothi, from a 10th century poem by the Icelandic poet Snow Bear, Lisa Collinson of the Centre for Scandinavian Studies at the University of Aberdeen contends Hamlet really derives from Admlithi of Eire in an Irish tale called the "Destruction of Da Derga's Hostel."
That it should come to this!
Since brevity is the soul of wit, I leave it here while Rossella Lorenzi at Discovery details the whole story.
