Are you confusing Proto-Nilo-Saharan maternal lineages for Bantu? Also, plenty of Somalis l has M or N lineages (which back migrated from the Near East). The majority of Somalis likely have indigenous HOA or NE African lineages (not outlier ones like you are proposing). Bantus are clearly a combination of multiple groups (with significant West and Central African). I think the OP got his 2% admixture from Kenya. You'll find more admixed Somalis from there than in other places. They tend to have nominal amounts though. And I'm referring to the ones originally from the NFD region.But it is NOT your maternal side that gave you the 2%. In fact, many Somalis have their maternal haplogroup as Bantu in Origin. So it is your paternal side that gave you the 2%.
