Are all the members of the family name (Al-Ahmar, Ahmar, lahmar, lahmer, lamar, lamer...etc) in the E-m2 of DNA ancestry?

DNA analysis is gaining the field day after day; So, peoples become nearer than before and the diversity is accepted more than before.

We want to know about the diversity between countries, orthography of the name and DNA. 

Could we be more precise about the number after (m), I mean E-m2(?)... ?
