The Dymen of
Hudson's River Y DNA Project Summary
The use of Y chromosome DNA (yDNA) technology for
surname studies began in 2001/2002. By capturing yDNA
from a simple inner cheek swab it became possible to
identify membership in specific defined paternal
This is not
the same as the commonly thought of use of DNA which
identifies an individual among a general population.It can
determine whether a male is descended from a common
father at some point back in time. It will either
include or exclude a male from membership in a specific
defined paternal lineage.
yDNA is passed father to son,
father to son down through time virtually unchanged.
Females do no have yDNA. yDNA follows the same path as
the surname making it ideal for surname projects and
biological paternal lineage studies.
The ability to define lineage signatures using yDNA
led to the yDNA study of the D*mon(d) surname in
Colonial America. Many nineteenth and twentieth century
genealogists and family historians guessed at connections
based merely on the common surname and geographic
location. yDNA has disproved many of these early published
trees and verified others.
spring of 2007 the yDNA signature of the seven primary D*mon(d)
surnamed American Colonial family groups had been defined
by their yDNA signature. At the same time their ancestral roots
In July of 2007 the Dymond Lineage of Hudson's River
(DHR) Study Project was spun off from the greater
D*mon(d) yDNA surname study. This was
to focus attention
on the Edward
Dimond family of Beekman Patent, Dutchess County, New
York Province c. 1720.
The DHR study
verifies descent from Edward Dimond and the resulting
haplotype data is collected, charted, and used in the
construction of an early family tree that conforms to
biologic possibility. This is important because records
in the pre 1800 years are few. Additionally those
familiar with the family will know that many given names
were used numerous times. For example the names Jacob
and John were given to many. Knowing which Jacob or John
a particular record is referring to has been a problem
from the beginning. yDNA has solved this problem.
DHR study is also actively research using traditional methods and in
collecting documents and photos.The study
is a means to connect cousins that family history may be

your participation or that of your male D*mon(d)

verifying early tree construction.
D*mon(d) and his descendants have been researched by many over the years and
three publications exist. All three are inaccurate to

dozen pages or so are especially inaccurate. Where the
book does well is the authors personal descent from John

Loyalist exodus to Canada. The greatest problem with
this branch tree is in the earliest generations. A

has been completed and is available.
The Settlers of the Beekman Patent, Dutchess County, Historical
and Genealogical Study of All the 18th Century Settlers in the Patent
4 by Frank Doherty
This is an amalgamation of the earlier two
previously mentioned works with the addition of Frank Doherty's
research related to his published series The Settlers of Beekman Patent in Dutchess County,
NY. Here too, in regard to the Dimond lineage, there are many errors.
The reason being that the Dimond tree outline was based
on the two earlier works picking up the errors within
them. The real asset of Doherty's work is in his
document research. The problem is in attribution of facts and the resulting tree.
There are now hundreds of Dymond-Diamond-Dimond
genealogies of this lineage in personal
ancestry program files and on the World Wide Web based on these

since the first was published. Errors have been found
and corrected. New branch linkages have been discovered

in the course of yDNA testing branch offshoots within
the lineage, a distinctly different Diamond/Dimond
lineage had been mistakenly included as descendants of
Edward of Beekman Patent.This lineage lived in the
Greenbush-Albany-Sandlake-Stephentown, New York vicinity
that Edward's descendants were living in the late
1700s. Previous researchers not having the benefit of
yDNA technology assumed these people were members of the
Edward Dimond lineage. Erroneous linkages were to
Edward's son Marcus 1726 and to Matthew 1740s son
yDNA has identified this NY lineage as
being a branch of the
Diamond/Dimond lineage of Newfoundland. The Newfoundland
branch is rooted in Europe and their history is of being a mariner-fishing family
the coastal waters from Newfoundland southward.
The project is exploring
whether they are linked to
the mariner-fishing family of Marblehead, Massachusetts
and/or that of the mariner-fishing-boat building-rope
making Diamond family of Kittery, and if they are the
source of the adopted D*mond surname of the Amerindian
Edward Dymen lineage.
The Dymen of
Hudson's River Study Project now includes both lineages.
They are labeled by their deep ancestral yDNA root.
Contact the study managers to discuss whether your
participation makes sense.
The study is open to anyone
directly descended from either lineage. If you wish to
participate contact one of the administrators listed below.
We would be happy to answer any questions you have.
**A WORD of CAUTION**
There are a number of genetic genealogy testing companies. They of equal quality. There
is also an array of testing
options and their practical use and value in genetic genealogy
is not the same. We have the knowledge and experience to keep you
from making mistakes, wasting time and money. Contact us so
that we can help steer you in the correct direction.
Testing Fund Grants
limited funds available for the testing of specific branch
lines. These are lines that have yet to have been tested and
their testing would be significant to the study going forward.
You Can Help
We would like to hear from you if you have branch family
information you would like to share, or correct/add to lineage histories, or to discuss the
Scans or photo
of early D*mond ancestor images (pre 1900) and other images such as
homesteads, gravestones, documents, records, etc. are appreciated
and add to everyone's experience.
