Welcome to the DUERINCK SURNAME DNA PROJECT (started year 2000)

[LAST REVISED February 23, 2007 (join the project link repaired, surname Dearinger added to list)] THE LIST OF DNA SURNAME PROJECTS, OR ONE-NAME STUDIES, HAS MOVED TO: List of DNA Surname Projects

NOTE: To join this project, go to: Duerinck Surname y-DNA Project Registration at FTDNA. The test results are at: Duerinck Surname DNA Project Results

So far the families Duerinck, Durinck, and Dierick are related.

Special thanks to my mom and dad, Louis and Pat Duerinck, who gave financial assistance to the DNA Project. A member of any of our variant clans may contact me for information on how to be tested to see if they are related to all of us. Their results would then be compared to our results which are in the Family Tree DNA database.



If you have come this far, you should probably have read a little about genetics and the y polymorphism and mtDNA methods, found under "Onsite Links" below. We, the Duerinck Clans, which includes all variant spellings for sake of simplicity, are faced with not joining up all of our clans by use of the convential paper trail. This paper trail basically consists of written birth, marriage, and death indices. In Europe, specifically Belgium and the Netherlands, we have run out of these types of records before 1600. The records in Germany are nonexistent in many cases. My clan, for hundreds of years in Puivelde, a hamlet of Belsele, Belgium, was originally from Sint Gillis-Dendermonde (around 1667). The paper trail, however, went up in flames in 1914 during a church fire. A Duerinck clan in the Netherlands likewise has met the same fate, with records gone in a fire. Therefore, we need to relate all of our clans by the scientific method -- by DNA analysis. We should at least be able to relate back to the times of the Germanic tribes in Germany -- you know, the Thuringii Tribe, possibly the Hermunduren (See the "Origin" pages). We call this calculating the Most Recent Common Ancestor (MRCA). And if the studies listed on the "Migration" page are any indication, it is ALSO possible to relate to 1 of the 10 sons of genetic Adam (y polymorphism DNA test) AND 1 of the 18 daughters of genetic Eve (an mtDNA test). People, no matter what country you are from, WELCOME to Genetics and Genealogy, or Genetic Genealogy, and the Duerinck Surname DNA Project! Welcome friends, lost relatives, distant relatives, and those just eager to drop by.

The Clans and Spellings

Over many hundreds of years, since surnames came into being, the variant spellings have evolved. Our surnames came from Germany. We have clans in Belgium, the Netherlands, and yes, in Germany. Additionally, there are families spread around the globe. Some of the spellings of OUR name are as follows: Duerinck, Duerink, Duerinckx, Deerinck, Durinck, Dierick, Dierickx, Duericx, Durick, Dieringer, Dueringer, Düring, Duhring, Doering, Doehring, Von Düring, and Thuringer. I personally do not know many of the clans/families in Germany, although I have been in touch with many variant-spelled surname clans there. I invite all of them to please join in the Duerinck Surname DNA Project. Let us unite to find our common ancestor.

Purpose of Project

My eminent colleague and fellow genealogist Doug Mumma, waxing eloquently, said it the best (I will change the names of course): The purpose of the Duerinck Surname DNA Project is, therefore, to perform Y chromosome DNA tests on a sampling of men with the "DUERINCK" surname (includes all variants), to calculate the Most Recent Common Ancestor for those surnames with a significant marker match, and to create a report describing the results. The report will then be available to all our clans worldwide.

The Plan

I propose that we perform Y-chromosome DNA testing for males who carry the Duerinck (or alternate spellings) surname. Participants from all of the various name spellings, including those that are not currently identified on the site, are encouraged to join in the test program. Each male participant would provide a mouth swab sample to be analyzed by a competent DNA laboratory to be chosen by Kevin Duerinck (after all of my research, trust me, please). 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. A standard swab kit is provided from the DNA testing laboratory. Each test kit consists of two cheek scrapers and two holding containers for shipping. The reason for two of each is to ensure a good collection of cheek cells for analyzing from at least one of the collection samples. Instructions generally insist that we use both. I would need 2 males from each clan to provide samples.

When we have enough participants, I will tell the lab how many test kits that I need. I would then send out the test kits to each participant. Each participant would then send his sample in with payment directly to me, and when I collected all of the kits, I would then send them in one shipment to the lab. I will require each participant to sign a waiver/release and consent form/letter of authorization allowing me to see all test results (in order to keep track of what clans are related). The analysis itself, after all samples are collected, takes about 5-6 weeks. All clans need to be aware that we are looking for lines of males genetically unbroken by adoption, illegitimacy, etc. I certainly do not mean to offend anyone, but if we test a non-Duerinck (or variant spelling), it will be a waste of time and money to the participant and the participant's family. Be certain that each of the clan's participants come from a long line of heredity, as far as the clan knows. If the results show "false paternity", meaning that the participant is not a Duerinck (or variant surname spelling), then the particpant will be informed discretely and should see a genetics counselor or medical geneticist for counseling.

Afraid of needles? No bother, because there are none! Step right up men! Be part of the NEW WAVE in genealogy! We need you! I don't know about restarting the Thuringii Tribe, but let's at least find our common ancestor, folks. Whether time, famine, pestilence, travel, war, or other factor has separated us, let us unite for this DNA Project! I myself will also be tested for mtDNA, which is extra. You know, if you are skittish about the cost, my brother Brian Duerinck, a great salesman, says it the best: "I know how you feel, all you have to do is just stick the swab in your mouth. ". Another one of his sayings: "I know how you feel, I felt the same way until I realized that $___ was a small price to pay. It comes out to be __ cents per year dating back to the 1500's. Yes, we can charge it (or expense it) to future generations.". Yes, Brian has a great sense of humor. I believe it is best if all your close family members chip in because the results are for them as well.


The following are the clans to be tested and the number of subjects committed so far. When replying to me, please send me your address, phone number, and what clan you are from. If I don't know your clan, then tell me who your direct ancestors were (and the place), going back at least 4 generations, if possible. I will cast the first lot and register under the Belsele, BEL Duerinck Clan. And please note that we always have room for clans with other like surnames, as well as room for more test subjects, just let me know.

The only issues preventing this project from instantly moving forward are money and participants. These tests are not inexpensive, although if you look at the history of the costs the last number of years, the costs are coming down. Depending on the number of individuals who participate, the testing costs will be less than US$199 (e-mail me if a member of a clan on this page for the exact cost) per sample (payable to the lab by money order or other guaranteed payment method, but sent to Kevin Duerinck for forwarding with the test kits), depending on how many participant samples are analyzed at one time. While it is desirable to test 20 individuals at once in order to obtain meaningful results, many of those doing surname DNA projects are getting 5 to 10 participants--the rest will have to be tested at a later time, then the results compared. I obviously don't have sufficient personal resources to fund the entire project myself. It is hoped that many of the participants will also feel that this project is sufficiently important to Duerinck surname research that they will be willing to pay the cost of the analysis of their own sample. I am continuing to negotiate with the various testing companies to obtain favorable prices for a large group of participants.


At the conclusion of the project, the summarized results (such as: this clan and this clan are related through a common ancestor around 1200 A.D.)will be posted on the Duerinck web site for all visitors and the participants of the program to view. The participants will not be identified by name unless they want to be. The DNA participants will receive more detailed messages and reports as the project progresses. In summary, we are testing so that we may relate all of our variant surname clans. The paper trail has run out--let science takeover! I am interested in finding out if clans are related to each other, and if yes, how long ago the common ancestor lived. SEE DOUG MUMMA'S PROJECT RESULTS--he has shown that a number of clans are related, but that some are not--powerful stuff! Be sure to see his chart of results toward the bottom of the page as well. Thank you for listening and I look forward to your active participation in this study. Click on my mail link at the bottom and give me some good news!


First of all, you should know that no medical tests are being run on your samples, therefore, there really is no privacy issue. However, your privacy is of concern to me and to many of the lab presidents to whom I have spoken. Complete privacy for each participant will be guaranteed. Each person will be assigned a sample number which only he (and I) will know. Any reports resulting from this test would only identify sample numbers, not individual names. The only risk of participating in such a study is that the participant might discover that he is not actually a male Duerinck descendant as he expected. This, of course, could happen if one of your ancestors was adopted and this fact never recorded. In addition, there could be the case where infidelity occurred with the wife of one of your ancestors. While we all don't think such events happened in our families, it can occur. Only an individual who did not test positive for one of the Duerinck lines and myself (the administrator of the project) would know that fact, so the individual himself would not be identified. However we would want to perform additional tests on other individuals in the same tree to determine where the surname link was broken.
