Leslie:
Did not find any Bronfman documents in my Bloomfield file, however when I was researching him I was focused on Permindex not the Bronfman family. Bloomfield was a well-connected lawyer and business man and am sure he knew them. His files are available online. If you want to review them I can show you how you can access them.
Found a letter in my files that was sent to Allen Dulles regarding a resume received from Bronfman's daughter, Mindy. Found this letter in Dulles' papers that are available online.
