WILLIAM
CAMPBELL
(OCTOBER 2014)
DNA WRITES
THE FINAL CHAPTER
[AN INQUIRY INTO
RELATEDNESS USING GENETIC GENEALOGY]
Genetic genealogy has produced a science-based
conclusion where traditional genealogy "came up short"
due to a lack of existing records. The central
question in this inquiry was whether or not the
William Campbell who lived out most of his adult life
in Ontario, Canada was indeed the same William
Campbell who was baptized by Sylvester Campbell and
Helen Mason on March 26, 1819. Through the facilities of Family
Tree DNA, samples were tested on a male descendant
of the William Campbell who resided in Ontario,
Canada and on male descendants of Adam Corbet
Campbell and George Campbell, already identified
and accepted as sons of Sylvester Campbell and
Helen Mason. Final genetic results became
available in October 2014. When compared against
the entire DNA database at Family Tree DNA, the
only "matches" identified by the Y-111 DNA tests
were these three individuals' samples with each
other. Family Tree DNA characterized these matches
as representing individuals whose male lineages
were "tightly related". Traditional genealogy had
already identified the relationship between these
three male lines as that of "third cousins". In short, William Campbell,
Adam Corbet Campbell and George Campbell were
scientifically demonstrated to be "genetic"
brothers. Two
additional analyses
carried out using the utilities at
Gedmatch.com placed the likely position of the
MRCA (most recent common ancestor) of three
tested individuals at 3.7 (4) and 3.8 (4)
generations respectively. Sylvester Campbell and
Helen Mason were the predicted four
generations removed from the current
individuals being tested in 2014.
The fact that all
three tested samples showed a "tight
genetic relationship" with an identified
genetic distance of only two and three
respectively and a predicted male MRCA
living four generations in the past
provides enough evidence for this
researcher to conclude that the
William Campbell who lived out most of
his adult life in Ontario, Canada was
the same William Campbell baptized by
Sylvester Campbell and Helen Mason on
March 26, 1819 at Drumoak,
Aberdeenshire, Scotland.
