Abstract
The nomadic Romani (gypsy) people are known for their deep-rooted traditions, but most of their history is recorded from external sources. We find evidence for a Romani genetic lineage in England long before their recorded arrival there. The most likely explanations are that either the historical record is wrong, or that early liaisons between Norse and Romani people during their coincident presence in ninth to tenth century Byzantium led to the spread of the haplotype to England.
