Dear Mr. Hosmer,
Thank you for posting your request on History Hub!
Please review The Hostages and the Casualties on the website of Jimmy Carter Presidential Library and Museum for a list of the 52 hostages. Also, we searched online and located photographs regarding a 2011 reunion at the US Military Academy (known as West Point) on Flickr and Defense.gov. Plus, we located newspaper articles about the event that provided information about some of the former hostages as of 2011.
We hope this is helpful. Best of luck with your research!
