In Jeffersonville IN, I met a man named Dana Olson who exhaustively researched and wrote a book about Prince Maloc in the late ‘70s. He couldn’t get it published, mainly because he refused to present it as a legend — rather, he insisted it was all true. He published via vanity press.
The book included a few photos: a sign erected by the DAR stating that On this spot in such-and-such a year Prince Maloc landed on the American continent.
The Rose Island bridge near Louisville constructed from large limestone blocks salvaged from a European-style fort found on the banks of the Ohio River by the “first” European explorers.
Also included was a list of Mandan words and their Welsh counterparts.
Olson was not a scholar. His book contained no footnotes or bibliography, nor did he mention any of his sources w/in the book. Still, there really was a lot there.
I have no idea how to get hold of Olson or his book. I met him in a bar, and he sold me a copy of his book out of the trunk of his car for $10.
