What does Fortunato’s name mean in "The Cask of Amontillado"?

In the short story "Cast of Amontillado" Fortunato is the character that is taken down into the wine cellar and sealed up in the stone wall to die.  This name is a very clever play on a name and creates irony in the story because the name Fortunato is "Italian, Spanish and Portuguese form of the Late Latin name Fortunatus meaning "fortunate, blessed, happy". This was the name of several early saints and martyrs."  How ironic that Fortuanto is the character that dies.
