Mormon prophet Joseph Smith Jr.,was definitely descended from Niall of the Nine Hostages, an Irish chieftain of the fifth century, Ugo Perego, a senior DNA researcher at Sorenson Molecular Genealogy Foundation has discovered.
See all of the Nibley-esque connections!

Seeing Niall's popularity among the nobles, Mongfind demands that Eochaid name a successor, hoping it will be one of her sons. Eochaid gives the task to a druid, Sithchenn, who devises a contest between the brothers, shutting them in a burning forge, telling them to save what they can, and judging them based on which objects they choose to save. Niall, who emerges carrying an anvil, is deemed greater than Brión, with a sledgehammer, Fiachrae with bellows and a pail of beer, Ailill with a chest of weapons, and Fergus with a bundle of wood. Mongfind refuses to accept the decision.
Get it? Anvil? Smith?
Sithchenn takes the brothers to the smith, who makes them weapons, and sends them out hunting. Each brother in turn goes looking for water, and finds a well guarded by a hideous hag who demands a kiss in return for water. Fergus and Ailill refuse and return empty-handed. Fiachrae gives her a quick peck, but not enough to satisfy her. Only Niall kisses her properly, and she is revealed as a beautiful maiden, the Sovereignty of Ireland.
There's a smith! And look, Niall's kiss reveals the supposed hag to be a beautiful maiden. Polygamy? Eh? Possibility? Kissing the maiden is tied to sovereignty! Dynastic polygamy? Eh?
Or maybe descent from Niall is not that special:
Early in 2006, geneticists at Trinity College, Dublin suggested that Niall may have been the most fecund male in Irish history. Of their Irish sample, the geneticists found that 21 percent of men from north-western Ireland, 8 percent from all of Ireland, a substantial percentage of men from western and central Scotland, and about 2 percent of men from New York bore the same Y-chromosome haplotype. The geneticists estimated that about 2–3 million men bear this marker, and concluded that these men are patrilineal descendants of Niall. According to Finding Your Roots, Niall of the Nine Hostages' descendents include Bill O'Reilly, Bill Maher, and Henry Louis Gates.
