DNA Chart For P*rdue Families From The Lower Appomattox River


DNA Chart For P*rdue Families From The Lower Appomattox River
The above chart shows the matches establishing the genetic profiles for John Pardue who died in Bute County, North Carolina in 1769, and for a William Perdue through his son, Francis, as shown on the patriarchial page of the Perdue/Pardue DNA Project,  and his presumed descendant, Meshack Perdue, who died in Franklin County, Virginia - both John and William early living in the colonial period in the watersheds of the Appomattox and James Rivers. 

The John, shown in the chart, born circa 1711, is the same John shown born circa 1705 and who died in 1769 in Bute County, North Carolina.  His son, John The Younger, born circa 1729/30, as determined by tithables' records, indicates that, while not improbable, it is unlikely, that the elder John was born as late as 1711. Descendants of the elder John's sons: Joseph, Bevel, Richard, and Lilliston were the participants who determined the elder John's DNA profile.  At the present time, while, it is definitively documented that Francis was a son of William Perdue, it has not effectively documented that Meshack Perdue was a descendant of William Perdue, though, their descendants share the same DNA profile. Remember, that DNA use for genealogy purposes can only establish genetic kinship, not the degree of kinship, at this point in scientific research projects.

The above chart shows a Joseph Pardue who died in 1845 in Chester County, South Carolina.  While some of Joseph's descendants claim descent from John Pardue who died in 1769 through John's son, Joseph Pardue, who died in 1790, at the time of this writing, there has been no documentation that can confirm descent from any of John's 11 sons.  And, though descent from John Pardue who died in 1769 and shown above as John Pardue born circa 1711, is a strong possibility, descent through Joseph, the third son of John, cannot be one of them, as shown by the following facts.

Joseph Pardue who died in 1790 did have a son named Joseph, but, as was stated in Joseph's will written in 1789, his son, Joseph was not yet 19 years old, putting his birth no earlier than 1770. The Joseph Pardue who died in 1845 was born in 1761 according to his tombstone records, further confirmed by 1780s Warren County, North Carolina tax records where he was shown as a single man, when he would have been at least 21 years old.

If the Joseph Pardue who died in 1845 was a grandson of John Pardue who died in 1769, the strongest probability of which of John's sons was his father lies with John's second, son, William Pardue, born circa 1731 and who died in 1813 in Warren County, North Carolina, where the younger Joseph lived in close proximity to William, from his marriage in the 1782 until his move to South Carolina between 1800 and 1810.  Unfortunately, William did not, from all the available records, appear to have named all his children in his will. A father often did not name the children to which he had previously presented to those children some form of his estate that he intended for them.

From research by descendants of the families who remained in the Virginia area, it is conjectured that Meshack was a descendant of the William shown in the chart.  But, at the time of this posting, the documentation necessary to confirm their relationship has not been established.  As previously noted in the earliest posting this webiste on the Perdue/Pardue yDNA Project, without documentation, dna testing, at the present time, cannot determine the degree of relationship each has to the other; only that within a parameter of generations they shared a recent common ancestor.  

As more participants of the Appomattox River P*rdue families join the dna project, updates of the information will be posted.  Any male with the P*rdue surname, or any variant, is encouraged to join the project.  As more participate in the project, at some future date dna might well be able, in some situations, to determine closer relationships.  Informaton can be obtained from the following website.  http://www.worldfamilies.net/surnames/perdue  

Also on the website project are links to explain how to read the test results, as well as other information that further explains questions wanting answers.

Called the Perdue Project, it was originated by descendants of the Perdue families from the Eastern Shore of Maryland, which until the advent of yDNA testing, researchers had never been sure that there was not an extant document somewhere that would establish a connection to the Virginia variant of the name. Now, it is known there is no common ancestral connection between the Maryland and Virginia variants of the P*rdue surname within the past one thousand years.

The Maryland Perdues more consistently spell their name Perdue, as do descendants of the Chesterfield County, Virginia Appomattox River families whose DNA matches the descendants of John Pardue of Bute County, whose descendants spell their names variously as Pardue, Perdue, and Purdue, as well as Pardew, Pardieu, and other variations, though Pardue is the more common form. As can be seen, yDNA is very helpful in sorting out whose lines belong to whom, and why males with any variation of surname spelling are encouraged to join this project!

Perdue/Pardue/Purdue y-DNA Project Update


Perdue/Pardue y-DNA Project Update 25 March 2011


The following  http://www.worldfamilies.net/surnames/perdue/results  links to the latest update of the Perdue/Pardue/Purdue y-DNA Project. 

After decades of research on the lines of Richard Perdue who died in Montgomery County, Tennessee in 1811 and whose sons and grandchildren moved into Illinois and Indiana, and unable to effectively connect him to the Richard Perdue in the family of eleven sons of John Pardue who died in 1769 in Bute County, North Carolina, DNA submitted by descendants of Richard demonstrates that Richard belongs to the Appomattox River Pardue/Perdue family and was the very probably Richard the son of John Pardue who died in 1769 in Bute County, North Carolina.  Unfortunately, the submitter did not provide a patrilineal history of the line of decent.

Once again, y-DNA testing has narrowed place and names in the search for ancestors and as time continues and the DNA research results become more established, DNA tests will continue to be a valuable research tool!

Perdue/Pardue DNA Project




The Perdue/Pardue DNA Project


If the male DNA matches up with another male participant possessing the DNA of a participant possessing the same or similar surname, it can confirm or not, whether there is a common ancestor and determine if you are on the right track in your research. However, only documented evidence can provide the degree of kinship to the common ancestor and it can provide a time frame of possibilities of when the common ancestor lived, but it cannot determine the exact relationship - only that there was one.

The Perdue/Pardue DNA Project at http://tinyurl.com/28lqje proves kinship through the P*rdue male line "Y" chromosome and must have a P*rdue surnamed male to prove ancestry. Females researchers should look to brothers, fathers, uncles, cousins, and grandfathers, etc. with the P*rdue surname to prove ancestry and males not possessing the P*rdue surname should look to the male line of their closest male kin with the P*rdue surname.

DNA testing of even so small a sampling of the participants in the above link to the project has determined that the P*rdue families early living in the watersheds of the lower Appomattox River area of Colonial Virginia had no kinship with the P*rdue families early living on the Eastern Shore of Colonial Maryland. And other participants in the project bearing the surname(s) or any of its variations show no kinship at all to either of those two larger groups of participants or even to each other.

The following list shows some of the possibilities of what DNA testing can do in the research for your family history:

* - determine if two people are related
* - find out if others with your surname are related
* - determine if two people descended from the same ancestor
     if the paper trail verifies the descent
* - provide an approximate time frame for the common ancestor
* - confirm your family tree
* - find others to whom you are related
* - determine a possible point of origin for your surname
* - prove or disprove a research theory
* - determine if other surnames are variants of your surname
* - for surnames with multiple points of origin, determine the possible points
* - provide clues for further research* - identify a location for further research
* - verify ancestors migration

To help interpret the above chart the following may prove helpful:
Distance Relatedness Explanation:

Tested at 12 markers:
Matches of less than 9/12 – the two participants do not share a common ancestor*
Matches of 9/12 - there is a tiny chance that the participants share a common ancestor. You'll need to test at 37 markers to find a true shared genetic match that starts with such a low match. (The author has not yet seen a 9/12 become an accepted genetic match - but knows of one case.)

Matches of 10/12 – there is a small chance that the participants share a common ancestor. Increase to 25 markers and re-evaluate Matches of 11/12 and 12/12 – an improved chance that the participants share a common ancestor. Increase to 25 markers and re-evaluate CAUTION: a 12/12 match - even with the same surname - can be a random match. If a solid paper trail connects the 12/12 match, you can be reasonably certain of shared ancestry, but without the connecting paper trail - you can only be sure by upgrading to at least 25 markers.
Tested at 25 markers:
Matches of less than 21/25 – the two participants do not share a common ancestor*
Matches of 21/25 & 22/25 – there is a small chance that the participants share a common ancestor. (Consider all of the traditional genealogy insights and try to obtain more participants to represent the affected families.) Upgrade to 37 markers

Matches of 23/25, 24/25 & 25/25 – there is a high probability that participants who share a surname share a common ancestor. If there is no shared paper trail, a comparison at 37 or 67 markers can be useful.

Tested at 37 markers:Matches of less than 31/37 – the two participants do not share a common ancestor*
Matches of 31/37 and 32/37 - the two participants have a small possibility that may share a common ancestor from the early days of surnames. (This is an area with little clear insight.) An upgrade to 67 markers is encouraged


Matches of 33/37 - some researchers consider this to be a match and some don't. (If there is a shared common ancestor - it will be more than a few 100s of years ago.) Upgrade to 67 markers for additional clarity
Matches of 34/37, 35/37, 36/37 & 37/37 - the participants share a recent common ancestor. 


Tested at 67 markers:
Matches of less than 60/67 – the two participants probably do not share a common ancestor*. (This is still being studied - but unless your match is nearly 60/67 and you have some reason to believe there is a shared ancestor since the advent of surnames - you should consider your near miss as "no match" )
Matches of 60/67 and 61/67 - the two participants may share a common ancestor from the early days of surnames. (This is still being studied)

Matches of 62/67 and better - researchers consider these to be a match - indicating a shared common ancestor.


* "We mean a common direct paternal ancestor within the historical period of surnames."
