Looking for any information on A2am mtdna lineage.
Maternal line traced back to Venezuela, end of the 18th century.
Phylotree : A2 (C64T) G16129A! T6253C T15229C G15314A

Here (https://www.mthaplogroup.org/) it is said that A2am was found in "Cuba, Dominican Republic, Haiti, Italy, Puerto Rico, Trinidad and Tobago, United States and Venezuela" without any information from where these data are coming.
According to these data, A2am seems to be mainly present in the Greater Caribbean, which may suggest that A2am was a Taino (arawak) or caribbean lineage.

The last topic treated by Bernard on his blog, is precisely related to the origin of your branch and in the paper* you can find a Mitochondrial DNA Phylogeny

Hi, there exist only 20 full mtDNAs assignable to A2am pubicly available so far, derived from USA and Puerto Rico. Assignation to A2m based only in HVR1+2 data based on the ´resence of 16129 can be missleading.

Best,

Claudio

Of course it is very interesting to see Russians (most likely they are not Russians, but peoples of Siberia) in the same sub-warehouse together with Greenlanders and Native Americans.

Thank you ! I did not know that Y full had also made a mtdna tree : on line since 14 march.

These lineages A2a and A2b1 were probably brought by the last migrations from Siberia to Alaska: paleo-eskimo (https://en.wikipedia.org/wiki/Paleo-Eskimo) or Thule people (https://en.wikipedia.org/wiki/Thule_people).

For me, since I have T6253C, T15229C and G15314A, I am A2am https://www.yfull.com/mtree/A2-a2/ like the 2 USA individuals, who are probably from Porto-Rico.

My mitochondrial DNA haplogroup is A2al. Is it possible to find out if someone is related to a specific tribe, like taino, looking at your mitochondrial haplogroup?

Hi there, I am also A2am, I was born in Cuba.

Just wanted to thank all previous members for the great references.

Hi Atteneri,

I am glad to know that you are also A2am.
It is interesting that you are from Cuba because it tends to prove that A2am was a Taíno lineage, or at least Arawak.

The majority of A2am are from Puerto Rico, and some, like me, are from Venezuela. I am working on the subject but it seems that most of the carriers of A2am who have a matrilineal origin in Venezuela could be all descendants of Leonor Lopez, wife of Alonzo Ortiz, notary writer of the "Armada", the Spanish Navy. Alonzo Ortiz is the drafter of the founding act of the city of Caracas, in 1567.
What origin were the matrilineal ancestors of Leonor Lopez, that remains to be found.

So far only one ancient DNA with A2am has been found in one of five Curaçao individuals found in a site related to Caquetio people (https://en.wikipedia.org/wiki/Caquetio), and dated circa 1300 CE, just before the arrival of Europeans.

Fernandes, D.M., Sirak, K.A., Ringbauer, H. et al. A genetic history of the pre-contact Caribbean. Nature (2020). https://doi.org/10.1038/s41586-020-03053-2
https://reich.hms.harvard.edu/sites/reich.hms.harvard.edu/files/inline-files/2020_FernandesSirak_Nature_Caribbean.pdf
https://reich.hms.harvard.edu/sites/reich.hms.harvard.edu/files/inline-files/2020_FernandesSirak_Nature_Caribbean_Supplement.pd f

It is however consistent with Taíno hypothesis because the same study says that 2/3 of ancestry in the 5 Curaçao individuals analyzed can be well-modeled as coming from a Caribbean Ceramic cluster, suggesting that there was major gene flow from the Antilles that affected Curaçao in the last centuries before the arrival of European.

Hi Hermelo

Without ancient DNA, it is only conjectures. It is assumed that such lineage originates from such ethnic group when we observe that the majority of contemporary testers come from an area where this ethnic group lived. But this still remains a hypothesis until archaeological and genetic evidences provide concrete proof.

For your haplogroup A2al, here blow the country distribution from public mtdna haplotree of FTDNA :

Spain 3 33.33%
Colombia 2 22.22%
India 1 11.11%
France 1 11.11%
Portugal 1 11.11%
Panama 1 11.11%
Unknown 3 **
Total 12 100.00%

We have Colombia and Panama as a possible place of origin for A2al. Interestingly, a recent study found haplogroup A2al in an individual from the African-American community of San Basilio de Palenque near Carthagena, Colombia. I am not sure if it is included in the FTDNA report above.
