Male Pedigree (Square) for Male Haplogroup H2a1 line and related YDNA Sample (BURXXX).

Extended Data Fig. 6 | Pedigrees from Phase 1. Circles and squares represent
females and males, respectively, while triangles represent unknown sex. Inside
each shape, individuals are labelled with their mitochondrial haplogroup
(first line), chromosome Y haplogroup (second line) and calibrated median age
(last line). Furthermore, solid black lines between shapes indicate well defined
first degree relationships, while stippled black and grey lines specify unknown
or uncertain first and second degree relationships, respectively. Panels a-g
represent Pedigrees 1.A to 1.G, respectively, whereas h) represents unrelated
individuals from Phase 1.

Summary of samples in pedigree 1 (Hap H) from study:
Pedigree 1.A is the largest of the Phase 1 pedigrees (Fig. 4a and
Extended Data Fig. 6a), containing 29 sequenced individuals and a
further 19 inferred individuals who were either not sampled or buried
outside the grave. All males in this group have Y chromosome haplogroup H2a1.
Three brothers (BUR222, BUR174 and BUR343) form
the first generation. Of these, BUR343 does not have offspring that
were buried in the grave, while BUR174 only has a single granddaughter.
However, BUR222 fathers four children (three sons, two of which
sequenced, and one daughter), and all of these children have children,
grandchildren and, in one case, great-grandchildren who were buried
within the grave.

The two sequenced sons of BUR222, BUR291 and BUR275, both
show long runs of homozygosity, with similar length profiles as
expected from parents that are first cousins (Extended Data Fig. 8a),
suggesting that BUR222 and the unsampled mother were third-degree
relatives. One of these sons, BUR291, has a further son (unsampled),
who conceived three children with one female, BUR262, who is a thirdor
fourth-degree relative to BUR291, her reproductive partner’s biological father.
The only sequenced son of this union (BUR316) also exhibits

long runs-of-homozygosity segments. Incidentally, BUR262 is also the
only female buried in the grave who has both ancestors and children
also buried at Bury.

One of the three brothers, BUR174, in the first generation of Phase
1 is also of some note. He was found as an almost complete skeleton,
in a seated position in the northeastern corner of the grave. The skull
had three perimortem lesions, each of which was caused by a blow
with a heavy and sharp instrument, theorized to be an axe19. Around
BUR174, three children and one perinatal individual were deposited
in a seemingly deliberate pattern. One of these children, BUR189, was
successfully sequenced and found to be an avuncular relation to the
three brothers. As they share the same mitochondrial haplogroup, it
is likely that BUR189 is the offspring of a sister to the three-brother
group. It is not known if the other children in the burial arrangement
are relatives, but given the high predominance of related individuals
in Phase 1, it is likely that these individuals were related to others. This
arrangement was previously hypothesized to be part of a ‘founding
act’ of the monument because of the position and characteristics of
BUR174 in the corner of the rear end of the grave19 (Fig. 1a). Given our
genetic results and BUR174’s position in the first generation of pedigree
group 1.A, this hypothesis seems likely.
