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

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!
