"That book"... hmm, this isn't ringin' a bell... maybe you're referring to one of David Rohl's books? He's an Egyptologist, he got interested in chronology revision and was active in the SIS (England) and the (failed) Glasgow Chronology. He's sure he's found the site of the Garden of Eden, the Tower of Babel, etc.
In Search Of Eden
Bad comms on my part. By “that book” I meant Genesis, first book of the Bible.
The website focused on the tribes and peoples of the period covered in Genesis and the geographic area involved.
Much larger and far reaching than I had thought when reading in sunday school as a kid.
