Dedicated to the preservation and restoration of genealogy and family history, through the combined efforts of those doing Mock family research, and seeking to find origins and interrelationships between various families in America and throughout the world.

All spelling variations of the name are noted in this non-inclusive list such as Mock, Mauck, Mauk, Mack, (germanic origin) Mauch, Muck, Mak, Moak, Maag, Maug, Maught and others.


FamilyTreeDNA began offering genealogy YDNA testing in 2000. Shortly afterwards, members of The Mock Family Historian chose to use this company so all our YDNA samples could be compared to one another.

Participation in the group is open to anyone researching their Mock, Mauck, Mauk, etc ancestors who submits a YDNA sample to FamilyTreeDNA for testing. When a YDNA donor joins the group FamilyTreeDNA feeds their test data into the Mock Group YDNA chart. Our group administrators can then compare the YDNA. If it matches YDNA already submitted the test results are placed together within a subgroup.

Part 1: DNA & Genealogy, Basic Overview

How Genealogy DNA Samples are Collected

Genealogy DNA samples are collected using saliva collection or a mouth swab. FamilyTreeDNA uses a simple mouth swab. You are provided with a container with a sterile swab along with instructions. The sample is collected by rubbing the sterile swab against the inside of your cheek, then sealed in the container and submitted for testing.

Different DNA Tests for Genealogy - Which One?

Marketing by the various companies who offer DNA testing is tailored to attract customers to their particular company. Most of these companies have created a significant amount of confusion as to the information their DNA test will provide and its accuracy. Most omit what it will not and cannot provide.

Different people have different interests when submitting DNA samples to one of the various companies who offer testing. What follows is a very brief synopsis of the types of tests currently offered and what they can tell you.

      Autosomal DNA (atDNA)
      Autosomal DNA testing is accurate for finding siblings along with 1st and 2nd generation cousins. Most companies who offer this test also offer general information on the general vicinity our ancestors may have come from. Autosomal DNA is not capable of tracing our family DNA to our ancestors the past 2000 years. This is the only test offered by Unfortunately, they do not identify which DNA test they do along with its strengths and limitations, up front. It's in their articles. "Ancestry® offers the autosomal DNA test, which produces the most comprehensive snapshot of one's ethnicity and living relatives."

      Mitochondrial DNA (mtDNA)
      mtDNA are the female sex chromosomes. They are used for researching maternal genealogy lines. When our mtDNA matches that of another submitter the likelihood our maternal lines are related increases significantly with each generation going back in time.

      X-Chromosomal DNA (X-DNA)
      Normally used in conjunction with atDNA to support relationship theories.

      Y-Chromosomal DNA (Y-DNA)
      YDNA are the male sex chromosomes. They are used for researching paternal genealogy lines. When our YDNA matches that of another submitter the likelihood our paternal lines are related increases significantly with each generation going back in time. Given the U.S. surname protocols that carry the male surname from one generation to the next, this is the test being used for the Mauck, Mauk, Mock ancestral DNA project.

All DNA used for genealogy is simply an investigative lead for further research. None of these tests can identify parentage or the specific ancestor we connect too. Even if they could, our ancestors didn't leave us samples of their DNA for comparison.

    • All DNA samples are compared to the DNA samples submitted by other descendants from all the different people of all surnames whose lines have survived over time
    • Descendant DNA eliminates the descendants we do not share ancestors with
    • Descendant YDNA and mtDNA identifies other descendants we do share ancestors with, along with mathematical estimates as to the number of generations back in time
    • DNA does not identify surnames or given names. These are provided through genealogy research.

Genealogy research relies on documentation and knowing where to look for it. Genealogy DNA, when combined with the genealogy research of others, can tell us where to look, sometimes breaching research brick walls. Just as important, it can tell us where, and on who, we would be wasting our research time.

The YDNA Test & How it is Used in Genealogy

The subject of DNA can be as complicated as you would like to make it. While the advanced levels appeal to some folks most of us prefer the basics.

This test examines a number of YDNA markers with the cost increasing with the number of markers tested. The greater the number of markers tested the tighter the connections become to others with matching markers. Over the years FamilyTreeDNA has offered a pricing structure for 12, 25, 37, 67, 111, 500, and 700 YDNA markers, with the option of upgrading to the higher numbers at any point later in time for the price difference (using the previously submitted sample). Currently, they offer 37, 67, 111, and 500. Throughout the year these are occasionally offered "on sale". The 12 and 25 marker tests have become obsolete with the hundreds of thousands of YDNA samples FamilyTreeDNA has received over the years..

The 37 marker test should be considered a minimum. The 67 marker test is a better choice if you can afford it. 111 markers helps narrow the generations down even more and is the best number for genealogy YDNA. The 500 marker test is not necessary for our purposes and not recommended for other than YDNA experts. Pricing and additional information can be found on the FamilyTreeDNA website by clicking here.

FamilyTreeDNA generates a list of DNA matches for you that, at a minimum, includes contact information for those have submitted samples that match yours. Additional information is optional and controlled by the person who submitted the sample. You control who can see your DNA. Like any other web based service, it requires a bit of exploring and learning but it's structured for simplicity with advanced being optional.

What YDNA can do for you:

  • Indicates which paternal lines, if any, are related
  • Rules out Mauck/Mauk/Mock paternal lines that are not related, significantly reducing your research time spent on unrelated families
  • Can verify if your genealogy research on your Mauck/Mauk/Mock line is correct (remember, us humans are human)

What a YDNA Test Will Not and Cannot Do

  • It cannot be used to establish parentage
  • It will not tell you exactly who your ancestors were (but can put you on the right path)
  • It is incapable and inadequate for use in genetic cloning (except in Hollywood)

Part III: Mauck/Mauk/Mock YDNA Chart


The chart that follows below is a hybrid of the Mock Group YDNA chart that appears on the FamilyTreeDNA website. The FamilyTreeYDNA chart has a number of limitations that prompted the construction of the chart you see below.

On it's surface, Genealogy YDNA can appear to be very complicated. For those who like complicated it won't disappoint you. Keeping things in their overall perspective, it's actually fairly simple. No amount of genealogy DNA knowledge can positively identify your specific ancestor. YDNA identifies descendants who have also submitted YDNA samples who share, or do not share, the same YDNA markers, to a greater or lesser extent.

As illustrated in the chart that follows, step back and look at the forest instead of focusing on the trees. The paths you see (colored horizontally) can lead you through the forest and show you where to look for your ancestors. Even better, they will show you which paths will get you nowhere (horizontal colors different than yours). The Ungrouped Subsection contains those who have not yet found a match. As more YDNA donors join the project this can change.

Where to look for your ancestors isn't in the forest. All you'll see there is trees (numbers). Where your path leads is to the names of your distant cousins who are following a branch of the same path you are following. Comparing their research with yours can produce some pretty interesting results. If all have done accurate research.

For an example, take a look at Group E (below). The research of Gerald and Walter Mock revealed they are descended from Peter Mack who died in North Carolina. Research indicates Peter was born in Germany, immigrated as a child, lived in Pennsylvania, and at some point moved to North Carolina. Now look at Daniel Jon Hay. Hay was adopted. His birth father's line goes back to George Mock who was born in Pennsylvania. George's parents were also born in Pennsylvania. There has been no evidence this part of the family tree went to North Carolina. Further research on George's parents and grandparents will likely lead to Peter's parents. A mystery many have not been able to solve. YDNA made this connection.

Another example. In Group C, Daniel Mauck and Mathias Mauk (the eldest Mathias) have long been suspected as brothers along with Rudolph Mauk of Bourbon County, KY. The YDNA from descendants of Frederick Mauk indicates he's also part of this family group within a generation or two. Frederick first appears when he bought land on Opequon Creek, VA in 1763. Daniel, Mathias, and Rudolph are believed to be sons of Rudolph Mauck (Sr.), who first appears in VA when his daughter Elizabeth was baptized by Lutheran Minister John Casper Stoever at Opequon 02 May 1736. This area of Virginia was largely wilderness at the time with the German Lutheran settlement at Opequon Creek being one of the first settlements in Northern Virgina.. YDNA revealed the connection between these groups. Where it prove even more valuable is in researching the parents of Rudolph and Frederick. Mathias (the younger Mathias), Cornelius, Franklin, Robert, and Joseph may be connected to Frederick through one of his grandsons. Or, may be part of the family of Gottlieb Mock who arrived in the Shenandoah Valley between 1790 and 1794. We are seeking a YDNA sample from a descendant of Gottlieb to see if he's part of this family.

  Kit Number & Name: The FamilyTreeDNA kit number and donor name
Paternal Ancestor NameThis should indicate the oldest paternal ancestor the submitter has researched their paternal line too. FamilyTreeDNA makes this field optional. The submitter can check their YDNA matches for the names. If no name is indicated they can contact the person who submitted the sample. One reason for this is privacy. Where this system fails is some of those who have submitted a sample change their e-mail address, don't answer their e-mail, pass away, etc. It also fails to show the branches of the paths through the forest.

Some people leave the field blank. Others indicate who they suspect their oldest researched ancestor is connected too. For this chart, I have attempted to verify each paternal ancestor indicated. Where none was indicated I researched the work of the submitter, if I could find it. Then entered the name, years, and locations. Those that remain blank I was unable to locate their research.

This information is a critical link between the YDNA and which family name/line it matches. Absent this information, the YDNA may fail to accomplish why it was submitted and what was paid for. If you know the paternal ancestor of a submitter for which this field is blank, please contact me.

  MFH Chart *: The Mock Family charts have been a long term effort to coordinate and share research leads. They are working charts, the info they have is not intended as "proof" of the accuracy of the info. These charts are a guide for further research. They should not be copied and used for anything other than research to prove the information they show.

I indicated the chart number that links to the oldest ancestor on the chart, if I could find it. If I could identify the line a YDNA donor was descended from, I indicated the location of their known ancestor on the chart (i.e. 1.3.5.)

For those with no chart listed, if you know their chart number, please contact me.

  Haplogroup: A group of YDNA donors who share a common paternal ancestor at some point in history. Confirmed and reliable for those who have paid for the "Big Y" test. All others are estimates by FamilyTreeDNA. Haplogroups are being used to point to different areas on the planet ancestors may have lived in. While interesting, haplogroup estimates are estimates. I've included links to information on each of the haplogroups shown.
  Red Background: Markers with faster mutation rates more likely to change within the past 15 generations.
  YDNA Marker DYS464:Occurs at least 4x. Fast mutating and can expand to 5x or 6x. Comparing those with 5 or 6 to those with 4 for genetic distance (differences) can become a bit confusing. Fortunately 4x is by far the most common. More detailed info may be found HERE.

Who to Contact for Further Information on the Families the Chart Shows

The Facebook page for The Mock Family Historian serves as a point of contact for those researching or familiar with these families. Please do not contact me for information on these families or their genealogy, the extent of my knowledge of these families is very limited.
