The information on this site has been documented to the greatest extent possible. Some
probable family relationships are included based on strong circumstantial
evidence. It should be noted that this is an on-going research project subject
to changes, additions and corrections as new evidence is revealed. A strong
motivation for publishing is the hope that doing so will attract constructive
comments which will advance the knowledge of these families. If you have
documented information to contribute, or have alternative theories or ideas
which should be considered, please contact Judy Stanley Cardwell or Thomas Stanley

Brief
Introduction into Y-DNA
Testing
This is a “brief introduction” into the new scientific field of
genealogical Y-DNA, as
it applies to this website. The modern advance of scientific research
in the field of Human Genetics, has opened up a new
and exciting study into the testing of the human male Y-Chromosomes. Through the marvels of microbiology we can
now very accurately test and measure this Y-Chromosome, which has certain
unique features such as; it is transmitted only from fathers to their sons, and
to their sons, and so on, it is also is generally unaffected by this exchange
from generation to generation, nor is it influenced by the mothers
X-Chromosome. Because these unique
features, the Y-Chromosome is very useful to genealogists. The Y-Chromosome has
definable segments of DNA known as Markers. These Markers, are
designated by a DSY number (D=DNA, Y=Y chromosome, S=a
unique DNA segment).
It is these Marker, and the
DSY# designation, and the Allele
(which is the number of repeats) that enables us to discriminate between
different male individuals. This
difference is the Y-DNA test results. Only males from the same family ancestry will
have the same test results! This Y-DNA
test results, when used as a genealogy tool, can determine with great
accuracy, if someone is or is not related.
To a lesser extent this same Y-DNA test result can
determine “about” when, these two individuals had a common ancestor.
Additionally, the Y-DNA test results provide
us with a broader classification working tool, called Haplogroups. These Haplo
types are genetic population groupings that identify where in the Y-DNA tree of humanity a individual fits in. Haplogroups
are what allow us to identify how large groups of people migrated from Africa around 60,000 years
ago to different parts of the world.
Male individuals of the same Haplo
type are much more closely relate, and those of a
different Haplo type. Male individuals of different Haplo types, are not
related at all!
