I have 14% Balkan/Greek DNA (which also comprises Albania, Romania and Hungary) and it is inherited from my paternal line. The paternal line had long held the David surname beginning with Ulrich David Runge, who dropped his original Runge surname upon migrating to The United States in the late 1800's. I'm convinced this percentage comes from him. I created a research article based on him. Below is the full breakdown of notable ancestors discovered through MyHeritage.

1. The Paternal Anchor: The Hunyadi / Corvinus Connection

The Notable Relatives by Genetic Distance table highlights two key medieval figures in Croatia/Hungary:

• Prince Johannes Corvinus (Genetic Distance: 4.128)
• Prince Christophorus Corvinus (Genetic Distance: 5.535)

Archaeogenomic sequencing of the Hunyadi (Corvinus) line published in 2022 confirmed that Prince Johannes Corvinus carried the E-V13 Y-haplogroup (sub-branch E-COR1). Matching the Corvinus family at a genetic distance of ~4.1 on an ancient origins panel confirms your paternal line shares the same deep Balkan/Danubian Y-DNA lineage.

2. The Carpathian & Balkan Cluster

• Hungary (4 samples): Aba Family (3.848), King Béla III (4.54), King Ladislaus I (6.02), Duke Béla of Macsó (6.303)
• Romania (1 sample): Báthory Family (3.99)
• Croatia / Hungary (2 samples): The Hunyadi/Corvinus Princes (4.128 & 5.535)
