Hafa Adai Sally, I am from Guam. My home is now is Lindenhurst, IL. I visted Guam last summer with my family and had a wonderful time. I bought this great book called " Ancient Chamorro Society". The book is written by Lawrence J. Cunningham. I'm sure you'll find this book fasinating. It will contain all the answers you need. I got it at a store called "Island Books". The store is located in Micronesia Mall. You could also find information on the Guam website. It's Guam.net. There's a lot on history. Also check out the website for the university of Guam. There is also another book by Dr. Katherine Aguon. I'm not sure of the name. I think it might be called "The history of Guam. If you would like to hear some Guam Music or buy some art work check out the web site www.peska.net
. I hope my information is helpful and I wish you luck on your research. Adios!
