While ago,at some of our forums,when we were discussed origin of name of Bogdan , Bratot has pointed some links with explanations that 
Bogdan originated from Theodore.
Precisely

I doubt that 
Origin of the word Bogdan according to letter changes researches is out of name of 
Macedon 
Македон 
because ,
M-> B
K->G

MaiKe
BaiGe
BaGa
Bog 


while for name of Theodorus 

Theodorus =Teos-God + dorus~gift 
My opinion is that Theόs has it's root at Deus ,and Deus or f. *Deusa has its possible origin in our word Dusa-Душа standing for Soul
