Dear Mr. Cox,
The Veterans Administration hosts an informative site about Agent Orange. There are several links available about to deal with and address it if you were exposed to it as well as the areas that could have experienced exposure. This may be a good place to find out about ships that may have housed Agent Orange. The National Archives at St. Louis has the Vietnam Era Mortuary Files and some of these may discuss those who suffered from Agent Orange. Additionally, we hold the records of Chemical Warfare Services that may be of interest.
We also conducted a brief search of the catalog using the terms Operation Frequent Wind, Operation Eagle Pull, and Agent Orange. We located a number of references to photographs and documents primarily held by our colleagues at the National Archives at College Park, MD related to these subjects. You can view and search the catalog here https://catalog.archives.gov/.
You can contact the National Archives at College Park at firstname.lastname@example.org. With any inquiry, please include your full name, mailing address, and contact information.
I hope this helps to put you in the correct direction to answer your questions.
