On Blood from Stones the author is Douglas Farah, do we know if he's related to Joseph? The book is not published by WND
I don't know if he is related.
I believe Farah is a common name.
I missed the discussion of the book. What's it about? (The back link didn't seem to mention it.) Farah is an Arab Christian name. The Farah Foundation, funded with money from the trouser manufacturing family, is a support for Orthodox Christian causes throughout the U.S.
Probably most of the Farah's in the U.S. are related, even if distantly.
