Really? That's funny because the national network of MLB said on the air that he was a distant cousin to Elvis Presley. Maybe the Pirates"spokesperson" is not aware of that.
Also, on the answers.com, it lists him and Elvis as cousins.

Another thing, I found out that there are two different blood lines of Presleys. One is Scottish which is Elvis', and the other is Irish which is not relation to Elvis. This would explain why there are so many Presleys throughout the nation. But the ones in the deep south who originate from Mississippi, Alabama, and Louisiana are mast likely related to Elvis.
