Does anybody know the name of one of Pound’s friends, living in New York in 1957 (but perhaps not prior to 1957), “whose fidelity [could] be counted on absolutely”?  
 
Possibly, one who was also eager to help liberate Pound?  And not necessarily famous or well known, outside of his circle of friends?
 
Thank you in advance for your help with this detail.
