PROJECT GOALS
The Davenport Surname DNA Project was
established in January, 2003, to create a database of DNA profiles of male Davenport
descendants to aid in genealogical research. DNA analysis can assist in
supporting or refuting the premise that two or more participants descend
from a common ancestor.
We hope to achieve the
following goals:
|
To determine possible relationships
between the known Davenport lines in the United States, and try to
discover how or if they are connected to Davenports in England or other
regions of the world. |
|
To determine possible relationships between other Davenport lines of
British descent (including those in the British Isles and other
countries). |
|
To assist Davenports not sure of their lineage and to determine which of these
broad groups they might fit into.

HOW TO JOIN
Since the lab is testing the y-chromosome which is only
passed down through an unbroken male lineage (father to son to son, etc.), you
must be a male with the Davenport surname to participate. Women who are
Davenport descendants may choose to sponsor a male Davenport relative (father,
brother, uncle, cousin, etc.)
Our testing company, Family Tree DNA (FTDNA), has given the
Davenport project discounted prices for the DNA tests. You can find more
information here: How Much does it Cost? . The preferred
test for our project is the shaded Y-DNA37, although the Y-DNA12 or Y-DNA25 will
also work. The 12 marker test will not be as useful as the other two. If at a
future date you would like to "upgrade" to a test with more markers then a
Y-Refine test may be used. No additional test kit would be required.
You may join the
DNA Project now by clicking on the "Join

you have any questions - contact the

TESTING LAB
Family Tree DNA (FTDNA), affiliated with Dr. Michael Hammer and the
University of Arizona, will be testing the Y-chromosome for genetic matches
between males. Results are placed in FTDNA's Y-DNA database and when 2 people
show the same identical results, the lab will inform both parties (provided both
signed the FTDNA Release Form). Project participants will receive a certificate
and report from the lab generally describing Y-DNA sequencing and the meaning of
the probability between matches.

DNA TO BE TESTED
Humans have 46 chromosomes. Our project tests only a
small portion
of the Y male chromosome at 12, 25, 37, or 67 marker loci sites. The results are
compared to those of other men who are potentially Davenport cousins. This test shows kinship
and nothing else. This is not a paternity-type DNA test like the U.S. military
now uses with all inductees; nor, does it test all 46 chromosomes to reveal
personal and private genetic information that some labs could use for medical or
insurance screening. Our project only tests part of the male Y chromosome.
Depending on the type of test, DNA testing and analysis will take place at the
University of Arizona Research Labs, or FTDNA's Genomics Research Center in
Houston. Upon completion, the results are returned to FTDNA and released to the Davenport project administrator and
the test participant.
A 37-marker test will provide a greater degree
of detail and visibility to genetic mutations and allow us to more effectively
use the results to sort the groups out. In very simplistic terms, the 37 marker
test effectively decreases the time back to the Most Recent Common Ancestor (MRCA)
by a quarter...from a 50% chance of a common ancestor in 29 generations to a 50%
chance in about 7 generations. If we assume a
generation averages 25 years, an exact match with a 37 marker test points back
to a MRCA born circa 1830 and a 12 marker test to a MRCA born circa 1280. In
other words - the 12 marker test can tell if there was a common ancestor within
the last several
hundred years, while the 37-marker can tell us if the ancestor was much more
recent. The 67 marker test can even be more precise.

DISCLAIMER, CONDITIONS AND
AGREEMENT
The Davenport Surname DNA Project organizers have no commercial affiliation with
any profit making organization and receive no compensation for services or
expenses involved with the project. At present, this webpage is maintained for
posting DNA results of participants who choose to make their
information available.
Although the Davenport Project has arranged for discounts at FTDNA, that by no
means suggests a business partnership or other relationship between the Project
and the Laboratory. All funds are payable only and directly to the testing
company.
The Davenport Project will not be the recipient nor steward of any DNA samples
and has no responsibility for their care, handling or return to participant, nor
duty to act on behalf of Participant in mediation of any dispute between the
Participant and the testing company.
While a match between two participants may indicate that they share a common
male ancestor, it will not identify the specific ancestor and there is no
guarantee that every participant will match another participant.
By participation in the project, the participant agrees to all conditions of the
Project.
