Nathan,
have you looked at the SWJ Blog review of 'American Guerrilla: The Forgotten Heroics of Russell W. Volckmann-The Man Who Escaped from Bataan, Raised a Filipino Army Against the Japanese, and Became the True "Father" of Army Special Forces by Mike Guardia. See:http://smallwarsjournal.com/blog/american-guerrilla
In the Comments there are IMO hopeful comments by 'Guerilla Daughter' and Jennifer Terrault who states:There is no email given, but 'Guerilla Daughter' appears to likely to have her email.My great grandfather was Captain Walter Cushing.
I only checked Google and the SWJ Blog piece was first! There are many entries on Google, but I assume you have waded through those.
I have emailed Nathan and 'Guerilla Daughter' - having connected her to the book's author in 2012.
