The Taxis DNA Project
This project will compare the Y-chromosome markers of male (patrilineal) descendants of Omodeo de Tassis del Cornello, who lived in the vicinity of St. Joannis Albi, near Bergamo, Italy, in 1251.
Through DNA testing, it is the aim of this project to see how, and if, men bearing the TAXIS surname, or one of its many variations, are descended from Omodeo de Tassis.
Taxis Family History
According to historians, Omodeo was part of the family that was originally known as the Torriani, or della Torre family.
The family was originally from Valsassina. In the 13th century, Pagano della Torre had rallied the Milanese after their defeat by Emperor Frederick, and thus gained political power in Milan.
Pagano died in 1241, after which his nephew Martino gained power and declared himself signore or lord in 1256. After his death, two other members of the Torriani family would become lords of Milan.
After the Torriani lost a battle for the domination of Milan to the Visconti in 1277, they settled near the Tasso mountains near Bergamo.
The family then became known as de Tassis.
Francisco Tasso, along with three of his brothers, ran a post service between Milano, Italy and Innsbruck, Austria. Francisco (later known as Franz von Taxis) moved from Italy to Brussels, and began a post service between that city and Vienna.
This horse-based system worked well, and the Habsburgs came to rely on it. Franz, and the family, were granted the right to carry government and personal mail throughout the Holy Roman Empire and Spain.
In 1512, the family received their Letters of Nobility from Emperor Maximilian I. These Letters of Nobility were confirmed in 1534, by Emperor Charles V. The family became Barons of the Empire in 1608; and in 1624, Counts of the Empire. In 1681, they were made princes
by the Spanish Court. Then in 1695, Emperor Leopold I of Habsburg, made the family princes of the Holy Roman Empire.
This was a large family, and they spread all over Europe to operate their postal service. The family name took different forms in different countries. Today, there are people with the surname Taxis living in the United States. There is also a family in Brazil, with the name of Tacques, who claim to be descendants of this famous family.

This project is open to males with the surnames: Taxis, von Taxis, von Thurn und Taxis, Tassis, de la Tour et Tassis, Tacques, and all of the other variations of the surname.
All male participants of the National Geographic Genographic Project who have the surname TAXIS, or one of its variations, are welcome to join the
Taxis Surname Y-DNA Project. Women who wish to participate in the project may have a male TAXIS relative take the Y-DNA test for them.
