Attention Ricardo Cortez fans!

I need your assistance. I am a film historian currently working on a biography of Ricardo Cortez to be published by BearManor Media. Am looking for personal information on him and backstory details of the making of his films. Am especially interested in communicating with anyone who knew and/or worked with him AND any of his relatives. If you have any info please contact me. Thanks so much.
