Jordan Radichkov ,never heard about him.I searched the web and found out he's bulgarian.That final "ov" is very often in bulgarian names,and in some russian names.
As for romanian writers...Mircea Eliade (he wrote a very interesting book about the history of religions) ,Emil Cioran and Eugen Ionesco (playwright;Ionescu was his real name,but "cul" means "ass" in french
,so when he went in France,he changed his name ) were the most (relatively ) known .None of them is alive now.
