Newly discovered Árpád dynasty members from the Ossuary of the Royal Basilica at Székesfehérvár
Three skeletal remains were newly identified as carrying the Árpád Dynasty's Y-chromosome haplogroup R-ARP5, based on the analysis of over 400 shotgun-sequenced genomes from the ossuary of the Royal Basilica of Székesfehérvár. Previously, four R-ARP5 individuals had been reported: King St. Ladislaus, King Bela III, one of Bela III's grandsons, and a modern individual (Yfull database?). With these new findings, the total number of known R–ARP5–positive individuals increases to seven. Kinship and IBD analyses were performed on these newly identified members, together with the remains of Bela, Duke of Macsó (c. 1243–1272), a Rurikid prince and great-great-grandson of King Bela III. One of the new R-ARP5 individuals was identified as King Bela II (the Blind, c. 1108-1141), and the authenticity of Bela, Duke of Macsó's remains was genetically confirmed. Another R-ARP5 individual is a second-degree relative of St. Ladislaus, though his precise identity remains unresolved. The third R-ARP5 individual, buried outside the original Basilica walls, was unrelated to the Árpáds. Genetic relatedness links Árpád members with conquering Hungarians and medieval noble families such as the Abas, Corvins, and Báthorys, consistent with historical records. Autosomal markers were also analyzed to reconstruct the physical traits of the newly identified individuals.
