    L2e is extremely rare so I'm not surprised that you have not found any information on it. I looked at the mitotool database and found 6 samples in GenBank and 1 in the 1000 Genomes study. If you tested the full sequence, you can compare your results to these samples to see if you match one of them more closely than the others.

    GenBankID, Author, country of origin
    EU092724, Behar, Guinea-Bissau-Mandinga
    DQ112709, Kivisild, Dominican
    FJ460523, Costa, Tunisia
    JQ044816, Barbieri, BurkinaFaso-Mande/Bias
    EF657291, Herrnstadt, Africa
    JQ045049, Barbieri, BurkinaFaso-Mande/Ssamo
    NA19108, 1000Genomes, Nigeria-Yoruba

    The Kivisild sample is presumably Dominican of African origin and the Herrnstadt study did not identify a country of origin, so only 5 of these samples are helpful for geographic origins.

    The common ancestor of L2 is estimated to have lived about 90,000 years ago, and L2e experienced a bottle neck of about 60,000 years, and is defined by 25 mutations that accumulated during that time. It's difficult to estimate the age of L2e given the small number of samples, but it might be approximately 20,000 years. So you definitely need the full sequence test to get a more precise estimate of your location in the L2e tree.

      L2e - Central Sudanics

      Nice to find another L2e

      My paternal-grandmother is L2e (L2d2); she's from a Central-Sudanic speaking tribe called Aringa (https://en.wikipedia.org/wiki/Aringa_people) in North-Western Uganda.

      This frequency map of L2e seems to be inline with Uganda's Central-Sudanic speakers migration from the West (illustrated in orange on the bottom map below). Many speakers of this Nilo-Saharan branch reside in south/central Chad and extreme-northern Cameroon.

      mtDNA L2d2 among different populations:
      Cameroon (Hide) [1/23]
      Cameroon (Fali) [1/41]
      Cameroon (Mandar) [2/37]
      Cameroon (Podokwo) [1/20]...


      Interesting enough, all the aforementioned Cameroonian ethnic groups are from northern Cameroon; some more specifically in the extreme north. Perhaps there's more L2e affinity with Nilo Saharan or Chadic speakers in and around the Chad basin -- that would explain L2e showing up among the small sample of Kanuri (Nigeria/Niger). "Kanuri (https://en.wikipedia.org/wiki/Kanuri...e-Decalo1997-5) groups have traditionally been sedentary, engaging in farming, fishing the Chad Basin, and engaged in trade and salt processing".

      I did a little more digging and found the publication below; it affirms the Chad Basin connection -- proportionately, the Buduma/Yedina (https://en.wikipedia.org/wiki/Buduma_people) have the highest detection of any population so far, I believe their sample size was n=30 (5/30, 17%)...

      "L2e (~47 ka) shows high frequencies in around Lake Chad: Buduma/Yedina, currently Chadic speakers (17% L2e and 30% L2a, b and c) and lesser among Fulani and Fali, North Cameroon, currently Niger-Congo speakers (3-5% L2e)."
