Resumo(s)
The presence of Africans in Britain has been recorded since Roman times, but has left no apparent
genetic trace among modern inhabitants. Y chromosomes belonging to the deepest-rooting clade of the
Y phylogeny, haplogroup (hg) A, are regarded as African-specific, and no examples have been reported
from Britain or elsewhere in Western Europe. We describe the presence of an hgA1 chromosome in an
indigenous British male; comparison with African examples suggests a Western African origin. Seven out of
18 men carrying the same rare east-Yorkshire surname as the original male also carry hgA1 chromosomes,
and documentary research resolves them into two genealogies with most-recent-common-ancestors living
in Yorkshire in the late 18th century. Analysis using 77 Y-short tandem repeats (STRs) is consistent with
coalescence a few generations earlier. Our findings represent the first genetic evidence of Africans among
‘indigenous’ British, and emphasize the complexity of human migration history as well as the pitfalls of
assigning geographical origin from Y-chromosomal haplotypes
