Okay. I don't understand that result, the less than 1%, or at least I don't know what it represents. African Ancestry doesn't consider anything less than 90% as a match, and almost always the matches they find are in the high 90s range, like the 97% you quoted. So the 1% is not a reference to the degree of match to the Temne tribe.

Perhaps they said that the mtDNA tested represents only 1% of your ancestry?? If that is the case, what they were telling you is that your mtDNA is from one line of ancestors and you have thousands of lines. The number of ancestors doubles each generation you go back; e.g., 2 parents, 4 grandparents, 8 great-grandparents, etc. By the time you go back 10 generations from you, you have 1,024 DIRECT ancestors (This is not counting aunts, not uncles, not cousins) and your mtDNA will not reflect any of the others, just that one.

Your "match" to the Temne could be 100%, but would still only represent a tiny portion of your ancestry. As an example, I have had four lines of my ancestry tested, and got 4 different results, each one a match. I am Tikar (Mother's mother), Mende & Temne (father's mother), Kru (mother's father) and Bubi (father's father). But that still is only 4 of the 1,024 ancestors I have at 10 generations back. I have no idea what the other 1,020 were.

Anyway, from my understanding of genetic genealogy testing, there is no way to tell WHAT generation came from Sierra Leone. It could have been 4 generations before you or 10 generations before you. This is where the old-fashioned genealogy work comes in.
