This project is a meeting place for users who share the A2am Mitochondrial DNA haplogroup, which means they are related along their maternal lines. Users in this group may want to share their family trees with each other to find overlaps and merge duplicate profiles in order to join or expand the World Family Tree and discover new relatives.
A2am
A2am is a subclade of mtdna haplogroup A [https://en.wikipedia.org/wiki/Haplogroup_A_(mtDNA)], downstream of his native american branch A2:

Ancient DNA
One A2am ancient DNA found in 2020 in Curaçao (I13472 - de Savaan), dated 660ybp, in an archeological context of Curaçao ceramic period (ca. 450 and 1500 CE). This paper shows that ancient ceramic individuals from Curaçao can be modeled as resulting from a genetic mixture between ancient ceramic individuals from the Lesser Antilles (74.5%) and ancient ceramic individuals from Venezuela (25.5%).
