Cetificado de ADN cromosoma Y

Los miembros del linaje de la Casa Grande de Lemavia proceden del Reino Unido, por estudios del cromosoma Y de los varones del linaje se ha establecido que en torno al siglo XI un varón procedente de las Islas Británicas se estableció en antiguo Reino de León fundando nuestro linaje.

Estos estudios han permitido encontrar en el Reino Unido 18 personas con 12/12 y 5 personas con 23/25 marcadores iguales, estableciéndose que procedemos del mismo antesapado por linea recta de varón, el cual vivió en el Reino Unido en torno al siglo XI.

Estos resultados coinciden con las tradiciones ancestrales, recogidas posteriormente en los Memoriales de la Casa que afirmaban que nuestro linaje procedía de un noble inglés que se estableció en el Reino de León durante el Reinado de Alfonso VI.

En la web vemos las ramas en las que se subidivide nuestro hapologrupo R1b1b2:

R1b1b2 Haplogroup R1b is the most common haplogroup in European populations. It is believed to have expanded throughout Europe as humans re-colonized after the last glacial maximum 10-12 thousand years ago. This lineage is also the haplogroup containing the Atlantic modal haplotype.

R1b1b2d Haplogroup R1b is the most common haplogroup in European populations. It is believed to have expanded throughout Europe as humans re-colonized after the last glacial maximum 10-12 thousand years ago. Its branch R1b1b2d is found primarily in the British Isles, but can also be found at lower frequencies around Western Europe.

R1b1b2e Haplogroup R1b is the most common haplogroup in European populations. It is believed to have expanded throughout Europe as humans re-colonized after the last glacial maximum 10-12 thousand years ago. Its branch R1b1b2e is primarily found in Northern Ireland, and contains the Niall Modal Haplotype.

R1b1b2g Haplogroup R1b is the most common haplogroup in European populations. It is believed to have expanded throughout Europe as humans re-colonized after the last glacial maximum 10-12 thousand years ago. Its branch R1b1b2g is distributed across Europe.

R1b1b2h Haplogroup R1b is the most common haplogroup in European populations. It is believed to have expanded throughout Europe as humans re-colonized after the last glacial maximum 10-12 thousand years ago. Its branch R1b1b2h is distributed across Europe.
