Results of DNA Tests for Lynn Edwin Garn

Types of DNA that were tested
and who the results also apply to

The DNA test that I took measured three types of DNA. These are autosomal-DNA, Y-DNA, and mitochondrial-DNA. These three types of DNA come from three different sources, have different characteristics, and reveal different information as noted below.

  • Autosomal-DNA - Applies to both Garn and Nixon/Holly cousins
    • Makes up the vast majority of DNA that was tested
    • Comes from all ancestors
    • Can not be associated with a particular ancestor without DNA tests on other relatives or genealogical records to supplement the tests. That is, if tests reveal that you are part Chinese and didn't know that a particular great-great-grandmother was Chinese, the tests will not tell you which ancestor was Chinese
    • Provides general information about ancestors who are not in the direct male line (Y-DNA) or in the direct female line (mitochondrial-DNA)
  • Y-DNA - Also applies to my Garn cousins (They have an ancestor with this Y-DNA)
    • Comes only from the father because only males have Y-chromosomes - Men do not pass any Y-DNA on to their daughters
    • Women may infer information about their father's paternal ancestors from results of a Y-DNA test taken by a brother or male cousin who is a Garn.
    • Conclusions drawn from results of my Y-DNA tests apply to my Garn cousins who are children of my dad's siblings and to all other descendants of any of my direct-line male Garn ancestors.
    • My Nixon/Holly cousins can not draw any conclusions about their ancestry from conclusions drawn from my Y-DNA test results.
  • Mitochondrial-DNA (mt-DNA) - Also applies to my Nixon/Holly cousins (They have an ancestor with this mt-DNA)
    • Comes only from the mother even though both parents have mt-DNA
    • Men receive mt-DNA from their mothers but do not pass any mt-DNA to their children
    • Men receive mt-DNA from their mothers and therefore can discover information about their mother's direct-line maternal ancestors from mt-DNA test results.
    • Conclusions drawn from results of my mt-DNA tests apply to my mother's siblings, their children, and all descendants of any of my direct-line female ancestors.
    • My Garn cousins cannot draw any conclusions about their ancestry from my mt-DNA test results.
In order to make it easier to understand which of my ancestors the three types of DNA tests apply to, I created a color coded table of a few generations of my ancestors. The chart below shows how the table is encoded.

Color Coding For Ancestor Chart
Ancestors from whom Lynn E. Garn received his Y-DNA are color coded gray
Ancestors from whom Lynn E. Garn received his mitochondrial-DNA are color coded aqua
Lynn E. Garn received Autosomal-DNA from all of his ancestors. Ancestors who provided only Autosomal-DNA are color coded pink

The chart below shows my ancestors going as far back as my great-great-grandparents. The various colors show which people provided my Y-DNA, my mitochondral-DNA, and my autosomal-DNA according to the color coding chart above.

Although the chart above shows my ancestry through only my great-great-grandparents, my genealogical research has uncovered several more generations of ancestors along some of the lines. Since Y-DNA test results follow my line of male ancestors and since mitochondrial-DNA test results follow my line of female ancestors, it may be useful to list a few more generations of my line of male ancetors and my line of female ancestors. These are listed below.

  • Direct-Line Male Ancestors - More of the Y-DNA line:
    • Stewart Darrel Garn < Archie Edwin Garn < Martin Garn < Abraham Garn < John Garn < Conrad Gern < Johann Adam Gern, < Johannes Gern
    • Test results and conclusions for my Y-DNA test also apply to everyone who is also a descendant of any of the Garn or Gern men listed above.
  • Direct-Line Female Ancestors - More of the Mitochondrial-DNA line:
    • Helen Frances (Nixon) Garn < Chloie Adell (Smith) Nixon < Clara Elizabeth (Hunt) Smith < Elizabeth Bridges (Butterfield) Hunt < Jemima (Averill) Butterfield < Mehitable (Bradford) Averill < Hannah (Goffe) Bradford
    • Test results and conclusions for my mt-DNA test also apply to everyone who is also a descendant of any of the women listed above.

Another thing that is worth pointing out in the chart above is that my great-great grandfather, Abraham Garn, married his second cousin Susanna Garn. However, the fact that second cousins married does not affect Abraham Garn's Y-DNA, the Y-DNA he passed on to his descendants including me, my Y-DNA test results, or the conclusions drawn from my test. It does mean, however, that Abraham Garn and his wife shared some common autosomal-DNA which increases the presence of Garn/Gern DNA in the autosomal-DNA pool that was tested. This does not decrease the credibility of the conclusions about the origins of my ancestors or their ethnicity. The increased presence of Garn/Gern DNA in the gene pool that was tested is reflected in the percentages of ethnicity measured and presented in the combined results and conclusions drawn from the autosomal-DNA tests.
