A genetic study published in "Nature Communications" in September 2018 found strong genetic similarities between Lombards of Italy and earlier Lombards of Central Europe. The Lombards of Central Europe displayed no genetic similarities with earlier populations of this region, but were on the other hand strikingly similar genetically to Bronze Age Scandinavians. Lombard males were primarily carriers of subclades of haplogroup R1b and I2a2a1, both of whom are common among Germanic peoples. Lombard males were found to be more genetically homogenous than Lombard females. The evidence suggested that the Lombards originated in Northern Europe, and were a patriarchal people who settled Central Europe and then later Italy through a migration from the north.
