I want to thank Moshe Pavlov for discovering a mistake I made in the naming conventions. I went back and checked my notes - discovering that I had indeed made a mistake. I have no reference for that title.
Thank you, Moshe for pointing that out.
Warm regards,
Jaim
This is the message from Moshe:
"Dear Dr. Harlow,
i liked your article on Abu al-barakat. How do you know that he was the son of a Cohen?
Thank you,
Sincerely,
Moshe Pavlov"
