Hi everyone,
I am curious if anyone else has run into very different ancestry results utilizing different services when it comes to identifying Italian vs Iberian ancestry. In my case, we know that my maternal grandmother was Puerto Rican, but we are trying to identify whether my maternal grandfather was one of two individuals, one who was Puerto Rican, and the other who was Sicilian (both deceased).
Unfortunately, the differing results between tests have not helped us to resolve this problem. My results through different testing services and analyses have been:
23 and Me
47.1% Ashkenazi Jewish
25% Iberian
0.7% Italian
10.2% Broadly Southern European
5.4% Native American
4% Sub Saharan African
7.6% Misc/Unk
Ancestry
48% Ashkenazi Jewish
11% Iberian
15% Italy/Greece
6% Native American
7% Africa
13% Misc/Unk
FTDNA
49% Ashkenazi Jewish
18% Italy/Greece
13% Iberia
6% British Isles
6% Native American
6% African
2% Misc/Unk
DNA Land
51% Ashkenazi Jewish
Southwest European/Iberian 27%
Italian 0%
African 13%
Native American 6.3%
2.7% Misc/Unk
Obviously with both populations being Mediterranean and there having been some degree of interchange between the two (Italians in Iberia during the Roman period and Iberians in Southern Italy/Sicily via the Aragonese, etc) there would be some degree of genetic confusion between them. But for the degree of Italian to range from nothing to 1/5th between tests seems unusual. Has anyone else encountered this?
