Testing my DNA?!? Are you nuts?!?!

If your PARR research has hit a “brick wall,” DNA analysis could be the break through you have been looking for, to push your PARR genealogy research back generations, by finding connections to other PARR family Lines.



How to Take a Family Tree DNA Test (It’s PAINLESS!)


N E W S   to be shared! => 14 May 2008 – Family Tree DNA stands above the competition.

Why Family Tree DNA testing is one of the SAFEST, most private tests anyone can take: as you will notice that they are NOT listed among the many databases who are guilty claiming ownership.

The purpose of this study will be to determine possible relationships between different Parr family lines of British descent, with the following priorities:

1) To test whether there may or may not be a relationship between the Parrs of Ireland and England. Our first goal is to solicit DNA contributors from all Parr family lines.

2) To seek evidence as to which Parr family lines connect where. Further Data is still needed to discover family connections.

3) To seek submissions of Parrs of other nationalities (Poland, Normandy, German) to see if a relationship exists between these Parrs and the British Parrs.

The PARR DNA Project will perform the Y-DNA Test on men with the PARR surname.

Family Tree DNA handles all testing, and Project Prices are in US dollars, for the DNA Test Kits are as follows:

Y-DNA12  – –  Male 12 marker paternal test….$ 99 (Group rate)
Y-DNA25  – –  Male 25 marker paternal test….$124 (Group rate)
Y-DNA37  – –  Male 37 marker paternal test….$149 (Group rate)
Y-DNA67  – –  Male 67 marker paternal test….$239 (Group rate)
Y-DNA111 – – Male 111 marker paternal test…$339 (Group rate)


Other types of tests you can choose from are listed and priced accordingly, and available along with an order form at the Parr surname project website.

DNA Briefly Explained


Each participant will also receive a certificate and report containing their personal test results. The staff of FTDNA will help you interpret the meaning of your test results.

The Group Administrator does the routine data management tasks thereby reducing the cost of the testing for the PARR family’s project. The Group Administrator will be Family Tree DNA’s direct link to the project. The Group Administrators for the PARR DNA Project are: Deborah Malafronte and Trish Parr

The Group Administrators will have access to a secure page where your project’s status is updated daily. Family Tree DNA will distribute legal release forms allowing for the sharing of the test results with the Group Administrator. Test kits and payments may be submitted individually or as a group to FTDNA for processing.

FTDNA will consult with the Group Administrators on the minimum number of test takers needed to reconstruct your family tree, depending upon how many branches of your family will participate in the project.


All Male PARRs are encouraged to participate in the PARR DNA Project. Because females do not have the Y-chromosome they can only participate through a male PARR relative (father, grandfather, brother, uncle, cousin). Each male participant needs to provide a mouth swab sample to be analyzed by Family Tree DNA. This sampling technique is painless and only involves the use of a swab to collect a small amount of cells from the inside of a person’s cheek. The participant administers the test in the privacy of his own home.

Each participant needs to send a pedigree chart to the Group Administrators. Instructions for filling in a pedigree chart come with a selection of file formats to choose from, making it easier for all.

The Pedigree Chart should go back as far as possible to show the PARR surname as can be documented. Please include as many birth and death dates and maiden names for the spouses as possible. It is not necessary to include dates for any living persons, only for the deceased. The Group Administrators will make sure to include your KIT results in all PARR Project results.

Family Tree DNA (FTDNA) will mail a “DNA test kit” directly to each participant. The Family Tree DNA test kit consists of two cheek scrapers and two collection tubes — designed for a single persons use. The kit also includes instructions for collecting your DNA sample, and a release form allowing for sharing of your group data results with others who exactly match. This release form is optional. For more information of FTDNA policy on confidentiality and releasing information see: Legal Issues and Release Form.

Each participant will collect his sample and return the kit to Family Tree DNA, along with the payment, to Family Tree DNA. FTDNA will provide the necessary instructions with the kit. Payment can be made by cheque or credit card.

Family Tree DNA (FTDNA) follows the most stringent guidelines for privacy. FTDNA controls the Surnames Database Library and test scores, while the University of Arizona controls and maintains your genetic assets on our behalf. Therefore, there is a double safety net. The first is maintained by Family Tree DNA according to State legislation guidelines and the other is maintained by the University of Arizona which is bound by both State and Federal privacy and confidentiality legislation.

Family Tree DNA accepts the responsibility to keep your specific data private, at the same time, making enough general information public to allow us to build a Surnames Database library to be used for genealogical purposes.


The basic test results help answer the question:

  • How many different common male ancestors are associated with the PARR surname?

With the addition of the oldest known ancestor, where they came from and when, we may also be able to answer the questions:

  • Are all PARRs from an ancestral country related, or are there many different families with the name PARR?
  • Can a connection between the PARRs from Ireland and the PARRs from England and Scotland be made?
  • How are the different PARR family lines related?
  • How are your PARR ancestors related to other families with the PARR surname?

Unfortunately these results as presented DO NOT answer the question:

  • Which PARR researchers should be collaborating because they share a common ancestor?

To answer this question you need to know who the participants are so you can collaborate with them. All participants are encouraged, but not required, to provide contact information so they and others can share information. After the information above is posted and participants have the opportunity to review their results compared to others, they will be asked to release contact information. They may agree to do so or decline. No contact information will be provided without a WRITTEN RELEASE FORM from the participant.

There is always a possibility that you could get disappointing test results. Samples that vary by three or more markers from the main group may do so for a number of reasons. One possibility is that they represent distinct lines either older or younger than the currently observed most frequent line. Another is that there has been a “non-paternal event” at an unknown past time. There are several possible types of non-paternal event in addition to a pregnancy gained outside of a marriage. For example, a child may be adopted and given the PARR name; a man may take the PARR name when he marries a PARR daughter; a PARR man may marry a pregnant woman whose husband has died; a couple where the wife is the PARR may choose to give their children the PARR name for various reasons; clerical error in recording administrative data may assign a PARR name to the wrong person, and so on.

It should be stressed that adoptions were quite common in every age (example: parents died by disease or war and a relative took in the children, and raised them with their surname; or young daughters had a child out of wedlock and the parents raised it as their own).

Some may not want to see a result indicating a “non-paternal event” but we are all legal PARRs and a small sample size could be misleading. One may get a DNA sequence which suggests a “non-paternal event” but they could be of the original blood PARR line. Let me explain. Twenty people are tested and 19 are very similar but the last is clearly different. It could turn out that the 19 descend from the same person 300 years ago and this person was an adopted PARR while the other is of the original blood line going back 800 years.RESULTS TO DATE The Parr Y-DNA testing results are available in Excel 2003 spreadsheet format. You will need to have Microsoft ® Excel 2003 or newer …OR… download a FREE Excel Viewer (you will need to scroll down below their rather large header boasting about Windows10 being available) and install it on your computer, in order to view the Y-DNA testing results.

Understanding DNA matches

* Haplogroups in green have been confirmed by SNP testing. Haplogroups in red have been predicted by Family Tree DNA based on unambiguous results in the individual’s personal page. This has been placed on this GAP page for your ease and convenience. Please note that for any predicted results we see no reason for ordering a SNP test to confirm the Haplogroup. If a – is in the HAPLO field then we feel that the comparative results are not clear and unambiguous and if the kit holder wants to know their SNP with 100% confidence they may consider ordering a SNP confirmation test.

Haplogroup Descriptions

N This haplogroup is distributed throughout Northern Eurasia. It is the most common Y-chromosome type in Uralic speakers (Finns and Native Siberian). This lineage most likely originated in northern China or Mongolia and then spread into Siberia where it became a very common line in western Siberia.

R1a The R1a lineage is believed to have originated in the Eurasian Steppes north of the Black & Caspian Seas. This lineage is thought to descend from a population of the Kurgan culture, known for the domestication of the horse (circa 3000 B.C.E.). These people were also believed to be the first speakers of the Indo-European language group. This lineage is found in central & western Asia, India, and in Slavic populations of Europe.

R1b Haplogroup R1b is the most common haplogroup in European populations. It is believed to have expanded throughout Europe as humans re-colonized after the last glacial maximum 10-12 thousand years ago. This lineage is also the haplogroup containing the Atlantic modal haplotype.

R1b1 Haplogroup R1b1 is the most common haplogroup in European populations. It is believed to have expanded throughout Europe as humans re-colonized after the last glacial maximum 10-12 thousand years ago. This lineage is also the haplogroup containing the Atlantic modal haplotype.

Here is Family Tree DNA’s take on Rb1 and R1b1:

About Your R1b Haplogroup

The R1b Haplogroup is the most frequently occurring paternal lineage in Western Europe, as well as some parts of Russia and Central Africa. The clade is also present at lower frequencies throughout Eastern Europe, Western Asia, as well as parts of North Africa and Central Asia.

The oldest human remains found with R1b so far are:

  • an individual known as Villabruna 1, who lived circa 14,000 years BP and reportedly belonged to R1b1a*
  • a male commonly referred to as the “Samara hunter-gatherer”, who lived approximately 7,000 BP in the Volga River area, who carried R1b1*

Why Join the R1b Group Project?

The goal of the R1b Group Project is to gain a deeper understanding of the origins and migrations of our male lineages as Haplogroup R1b. The project is run by Mike Walsh, a volunteer Group Admin and knowledgeable genealogist.

By joining the project, Mike will help you:

  • find more information about your paternal lineages and deep ancestral origins
  • identify where you fit within R1b and get you to the right subclade project

What is a Group Project?

Group projects are FREE to join. Each group project is run by volunteer Group Administrators who can help you better understand your results.

Group Projects give you an opportunity to work with others to explore your genetic heritage. They are usually focused on a common geographic origin, surname, or ethnic heritage. Projects are designed to help individuals who may have similar ancestry connect with one another.

DYS 19 is also known as DYS 394.

A value of “0” for any marker indicates that the lab reported a null value or no result for this marker. All cases of this nature are retested multiple times by the lab to confirm their accuracy. Mutations causing null values are infrequent, but are passed on to offspring just like other mutations, so related male lineages such as a father and son would likely share any null values.

It is obvious from our observation of 10’s of 1000’s of samples that some markers change or mutate at a faster rate than others. Therefore not all markers should be treated the same for evaluation purposes.

The markers in red have shown a faster mutation rate then the average, and therefore these markers are very helpful at splitting lineages into sub sets, or branches, within your family tree.

Explained another way, if you match exactly on all of the markers except for one or a few of the markers we have determined mutate more quickly, then despite the mutation this mismatch only slightly decreases the probability of two people in your surname group who match 11/12 or even 23/25 of not sharing a recent common ancestor.
