m1a3b haplogroup- origins, info?

[grapefruit]

Based on 23andme results my mother and I both have this haplogroup. It says it is from ethiopia/found in North Africans and some Jews, and some Slavic populations but I can't find much more detailed info. My mother has Jewish ancestry but from her father, her mother is fully Russian.

Is anyone else on here from this haplogroup? It seems uncommon.
