A recent study indicates that up to three million men globally may be descendants of Niall of the Nine Hostages, a fifth-century Irish king, with research suggesting that about 1 in 12 men in Ireland carry his genes. This study supports the idea that Niall founded a dynasty that significantly influenced Irish history. The discussion raises questions about the implications for these descendants if Niall's existence were disproven, humorously questioning whether they would "evaporate." Additionally, it is noted that many individuals of Irish descent likely carry genes from early ancestors of the Ua Niall clan, regardless of the historical accuracy of Niall's existence, similar to the uncertainty surrounding Genghis Khan's lineage.
