J1b two clusters - Northern Iranian and Luso-Brazilian

J1b M365 has a very rare Y STR motif. 393=13 390=22, 19=15, 385a=12, 388=16, 458=458,2 YCAIIa =21, YCAIIb = 22. I have found two geographically well defined J1b clusters. There’s the Western Iberian, basically a Portuguese cluster, Old Christian (Cristão Velho), Catholic, J1b cluster found in Portugal, Minho, Azores, Portuguese borders (Galiza, Extremadura) with a regular expansion and presence in Brazil. In the FTDNA J Y DNA Project the Western Iberian cluster is easily recognizable. The other discovered cluster has been the Northern Iranian cluster.

In 2009 Professor Klyosov kindly calculated the TMRCA
001_Portugal 13 22 15 11 12 20 11 16 11 13 11 30
005_Brazil 13 22 16 10 12 19 11 16 11 13 11 29
007_Belgium 13 22 15 10 11 17 11 15 12 13 11 29
009_Azores 13 22 15 10 12 19 11 16 11 13 11 29
010_Spain 13 22 15 10 12 19 11 16 11 13 11 29
012_Brazil 13 22 15 10 12 19 11 16 11 13 11 29
013_Ferrere 13 22 15 10 12 19 11 16 11 13 11 30

The J1b cluster of 7 haplotypes should give the following time span to the common ancestor: 1725+/-570 years.

Now I have more markers from the SMGF (Sorenson Molecular Genealogy Foundation). The Iranian haplotypes are concentrated in the Northern Caspian area, Gilaki, Rasht, Astane, Talesh, Rezvanshar, Mazandarani, Tehran, Fars

Gonçalves (Brazilian -SMGF) - 37
Ferrere(Ferreira) 37/33
Abadeh 37/31
Tehran 37/30
Shahroud 37/26

Ferrere(Ferreira) (Portuguese-Reunion-SMGF) - 37
Gonçalves 37/33
Abadeh 37/30
Tehran 37/29
Shahroud 37/26

RCO (Ricardo Costa de Oliveira, Brazilian FTDNA/SMGF) - 28
28/24 Ferrere (Ferreira)
28/22 Gonçalves
28/22 Tehran
28/22 Abadeh
28/20 Shahroud
27/19 Astane

Dominguez – Galicia, Spain, FTDNA/SMGF 28
28/25 Gonçalves
28/25 Ferrere (Ferreira)
28/24 Abadeh
28/23 Tehran
28/22 Shahroud
27/21 Astane
27/19 Rezvanshar

Cordeiro de Melo (Brazilian - SMGF) – 32
25/24 Dominguez
25/20 RCO
32/29 Ferrere (Ferreira)
32/28 Gonçalves
32/26 Tehran

Tehran (SMGF) - 37
37/30 Gonçalves
37/30 Abadeh
37/29 Ferrere (Ferreira)
37/26 Shahroud
36/27 Astane

The Northern Iranian and the Western Iberian clusters are forming a perfect continuum of haplotypes. The Iranian cluster is the older and the most diverse cluster but there’s no distinct DYS maker in the SMGF 37 makers specific to differentiate any of the two distant geographical clusters. I keep the idea that a unique cluster can correspond to a unique historical event linking directly an Iranian speaking population to Western Iberia, the hypothesis of the Alan migration and invasion of Lusitania in 409 AD.

H1 mtDNA 16262T 16278T HVR1 as a genetic signature of the Portuguese maritime expansion

I have the rare HVR1 16262T 16278T 16519C mtDNA belonging to haplogroup H1

Frequencies of the rare 16262T, 16278T motif in three different databases:

SMGF Brazil 1348/2 (Rio de Janeiro and Santa Catarina)
FTDNA 430/2 Portugal (Brazil and USA with documented genealogies to the Ribeirinha, Terceira, Açores, Azores)
Terceira Island 18/2, Azores (total) 120/2
Mitochondrial DNA patterns in the Macaronesia islands: Variation within and among archipelagos
http://www3.interscience.wiley.com/cgi-bin/fulltext/122687703/sm002.xls?PLACEBO=IE.pdf

In the H1 FGS Project the next close match (without the rare 16262T) is RY9WZ from Valladolid, Spain at the cluster Z1a, but there’s a good distance. So that’s an old Iberian lineage
http://www.familytreedna.com/public/mtDNA_H1/default.aspx?section=mtresults

The 16262T 16278T motif seems to be related to a single woman as a founder colonist in the Terceira Island, Azores. That’s a presumable representative of the first Atlantic embarked European mtDNA in the 15th century and it’s an ethnic and national genetic signature of the old Portuguese Empire. Usually the Portuguese haplotypes are distinctively found clustered only in the Western Iberian Portuguese speaking areas and in the main Colony of Brazil as their big territorial expansion.

The theory of sampling obeys the principle of statistical regularity and the 16262T 16278T mtDNA genetic signature presents specific frequencies and the haplotypes can be analyzed as a more or less regular percentage found in diverse samples from the Azorean and Brazilian populations.
