R1b -V88 is a y-dna clan from among the Tribe of Levi. Those belonging to R1b- V88 haplogroup are the Sons of Levi descended from Moses. Some of the R1b V88 found in Africa may be the descendants of Moses and his Cushite or Ethiopian first wife Princess Tharbis who he married after he conquered Ethiopia (see Josephus). The R1b -V88 ydna in the Levant and found among Jews may be from Moses and his Midianite wife Zipporah. There have been many claims of both Jewish and Levite ancestry of different African tribal and clan groups. From my own studies of ydna it is clear that those Africans of R1b V88 ydna are certainly patrilineal descendants of the Tribe of Levi and in particular from Moses.
A large portion (40 %) of the Hausa people of Africa belong to R1b V88. Hausa is a semitic language closely related to Hebrew and Arabic. Hausa is part of the Chadic language group of whom many are of R1b V88. These people besides speaking a Semitic language are cattle raisers and milk drinkers like the ancient Hebrews and the R1b and R1a peoples of Europe. Their nobility are also great equestrians.The Fulani also have a large percentage (54%) of R1b V88. These African Sons of Moses were descended from a son of Moses (ancestor of R1b V88) and Princess Tharbis (possibly of U3 mt-dna) and they founded a Matriarchal line of Ruling Queens until the arrival of Bayajidda (possibly of Jewish E1b ydna from the Levant) who married the Mosaic Queen and the founding of the 7 Hausa kingdoms by their sons. E1b today makes up about 12-13 % of the Hausa people.
Some scholars believe that the Hausa peoples came into the Nigeria region from Nubia (in Sudan). Ten percent of Nubians today have R1b V88 ydna. It may have been that the Hausans were those Nubian Sons of Moses that refused to embrace the new Christian religion and clung to their form of mixed Tribal-Judeo religion and moved west to central western Africa around the 6th century. Most of them later embraced Islam mixed with their Tribal-Judeo beliefs.
It would also seem that many Samaritans of haplogroups J2 and E1b also moved into Africa which also led to many Africans to claim Israelite or Jewish origins. The Igbo of Nigeria claim Jewish ancestry and they are most likely mostly descended from the E1b Levites of the Samaritans. As many Samaritans joined Judaism in Second Temple Times the Igbo may indeed be descended from Jews of Samaritan Levite ancestry that moved to Africa and intermarried with Black African women. In the past I have thought that haplogroup E were the descendants of Nimrod (and thus Hamite) but reviewing this it is more likely that E haplogroup is Japhethic of the Javanite branch.
However on a purely patriarchal male line of descent it is only the R1b V88 that are direct male-line Israelites among the Black Africans. Maternal Israelite mt-dna lineages of J1b and H are also found among the R1b V88 populations. The other maternal lineages are V, U5 and U3. It would seem that these Black Israelites descended from Moses and Tharbis embraced a form of First Temple Judaism at a later date mixed with African and Egyptian pagan beliefs. In the sixth century AD some embraced the Christian Coptic religion while the rest moved west and later embraced Islam along with some of the formerly Coptic Christians of R1b V88 y-dna. Even today 15 % of the Sudanese Copts are R1b V88.

Note: The Kohanim (priests) and Leviim descended from Levi and Aaron mainly descend from among the Eastern Judahite R1b L23+ L51- (Ht-35) but some clans of Levi may also be found among Western Leahite R1b L51+ (Ht 15).
