Paternal Haplogroup Origins J-M304
Your paternal lineage may be linked to men who spread the Semitic languages
Men carrying the J-M267 lineage took part in many waves of migrations over the millennia, and domesticated animals and plants weren't the only things they carried. They may also have been among the communities that spread the Semitic languages, a diverse group that bloomed from a single proto-Semitic tongue in the Levant nearly 5,750 years ago. These men likely carried branches of both haplogroup J and of the Semitic language family through the Arabian Peninsula to the Horn of Africa. Still later, some J-M267-bearing men re-expanded from the Arabian Peninsula back through the Middle East and across North Africa in migrations associated with the emergence and spread of Islam.
Your maternal lineage may be linked to Marie Antoinette
Because it is so dominant in the general European population, haplogroup H also appears quite frequently in the continent's royal houses. Marie Antoinette, an Austrian Hapsburg who married into the French royal family, inherited the haplogroup from her maternal ancestors. So did Prince Philip, Duke of Edinburgh, whose recorded genealogy traces his female line to Bavaria. Scientists also discovered that famed 16th century astronomer Nicolaus Copernicus traced his maternal lineages to haplogroup H.
