Ety-what-mology

Hay guyz,
What is the most "spread-out" name you can think of? That is, a name that is used by the most amount of different countries including their respective variations.

If you count variations, John (masculine) has a ton. On the top of my head:
Johannes - Latin, Scand., Finn, German, Modern Roman, Greek(?).
Jan - Scand., Slovak, Polish, German.
John - English.
Johnny - English.
Juho (Juhho?) - Finnish.
Yann - Breton
Jean - Italian, French.
Juan - Spanish, Chinese, Italian(?), Japanese(?).
Jovanna (Or Jovana?) - Serbian
Iancu - Romanian

I've heard that the most common name in the world is Mohammad (including all the spelling variations).

>>5 I think this is actually correct... I've always thought John/Johannes and its million variations would top it though.
