Was Hamlet Irish?

Okay, you're right - today is St. Patrick's Day so perhaps I'm looking for some way to tie Kill Shakespeare with the celebration of the Irish.  But an interesting article from Discovery.com was forwarded to me by our friend Vanessa King two weeks ago, which stated this:Perhaps Hamlet was Irish.

The article discusses a recently-released research project in the Review of English Studies that states that a reference to a figure named Admlithi (the "D" is silent), which could be the variation that Shakespeare used to craft the melancholy Dane.
