So without further ado, here are my results:
Here's what Wikipedia says about the L3 Haplogroup:
It is most common in East Africa, in contrast to others parts of Africa where the haplogroups L1 and L2 represent two thirds of mtDNAs.
L3 is sub-divided into several clades, two of which spawned the macro-haplogroups M and N from which the vast majority of non-Africans are descended.
One of these lineages, defined by loss of the DdeI site at np 10394, represents only a few percent of the African mtDNAs but appears to be the progenitor of roughly half of all European, Asian and Native American mtDNAs."
According to Maca-Meyer et al. (2001), "L3 is more related to Eurasian haplogroups than to the most divergent African clusters L1 and L2". L3 is the haplogroup from which all modern humans outside of Africa derive.
And here's what it says about L3e specifically:
L3e - West-Central Africa. It is the most common L3 sub-clade in Bantu-speaking populations. L3e is suggested to be associated with a Central African origin and is also the most common L3 subclade amongst African Americans, Afro-Brazilians and Caribbeans
Now, I have only just begun to do some research on the L3 Haplogroup. Hopefully, I will be able to find out more information that will allow me to narrow down further from which people or country my DNA originates from. I will keep you posted on what I find out. Perhaps some of you out there have tested your MtDNA as well. Feel free to share in the comments your findings.
