Before the development of this method of translation, little more than dates could be deciphered from archaeological findings. With the new procedures, however, significant new information is now coming to light. For example, the name of the Jaredite king Kish, as well as his birthday, birthplace, and the day he ascended to the throne, may have been deciphered.Interestingly, while looking up some information on the well established Mesoamerican name Xul, known both among the Olmecs and the Mayans (a relatively common name, still in use, as I understand - it was also the name of a Mayan month), I found it is also preceded by the term "Kan" in another person's name from Palenque, as shown on the page http://www.jaguar-sun.com/glossary.html or at a page from the Colorado School of Mines. Xul is pronounced as "Shule" and may correspond with the Jaredite name Shule in the Book of Mormon.
On the Tablet of the Cross at Palenque are found engravings that trace the genealogy of Kan Balam, the son of King Pacal, who is buried in the great tomb there. Among the names of Kan Balam's royal ancestors is found what may be the full name of King Kish_U-Kish Kan, an ancient king of the Olmec culture.
Kan means serpent. One of the meanings of Kish is feathered. Now that the Maya code is being deciphered, the name of U-Kish Kan has been translated as "he of the feathered serpent."
This symbolic connection between U-Kish Kan with the feathered serpent suggests a relationship to Jesus Christ, whom the Jaredites knew to be the Mesoamerican Messiah or the white god of Mesoamerica who is also known as "the feathered serpent."
There are many other Book of Mormon names that appear to be authentic ancient Semitic names. It's interesting that tentative links to Mesoamerican names are also beginning to appear. An understanding of ancient Mesoamerica is many years behind our knowledge of the ancient Hebrews, of course - stay patient and stay tuned.
