Two women in England, Doreen Isherwood and Anne Hall, have learned that their mitochondrial DNA is Native American.
Indigenous Americans were brought over to the UK as early as the 1500s.
Many were brought over as curiosities; but others travelled here in delegations during the 18th Century to petition the British imperial government over trade or protection from other tribes.
Experts say it is probable that some stayed in Britain and married into local communities. [Link]
