Hi everyone !

My fatherline is from Aures mountains in Algeria, from a berber background called Shawi people. My Y haplogroup is E-V13 (old E-L250) but it seems that there's not more than a single percent of this haplogroup there, and I haven't more details.
Can I found a way to estimate its origin ? Did it came in Algeria with Byzantine or during classical era while Cirta was a multicultural city ? I know some shawi tribes have been founded by lost romans (or rumi), can it be linked ? Or is it more of iberomaurissian roots ?

Sorry if it's not the right place, and thanks for any help.
