Sister ?

Research on the Mitochondrial DNA (mtDNA) results of the family are fascinating. Mitochondrial DNA is passed only from your mother, unlike your nuclear DNA which you inherit from both parents. Read more at wikitree, but just one finding of the research is that Ansela and Iba could not have been biological sisters (confusion, I thought they were mother and daughter?), as their descendants do not share the same mtDNA haplogroup. One of Ansela’s descendant’s results yielded identical matches to:
1 African American individual
1 individual from the Democratic Republic of Congo
4 Zanzibaris
2 ‘South African Coloureds’
1 ‘South African Indian’
1 ‘South African White’
67 South African Bantu-speakers.
