These results are identified by the Kit number and name of the tester, and the name, date, and place of the earliest proven or suspected ancestor.

These results were last updated on May 12, 2008.

A simple explanation of the chart below: The test you took was either a 12, 25, or 37 marker test. Your DNA report will list the names of the markers that were tested in the top row, ie. 390, 393, 19..etc. Below the names of the markers are your test results, ie. 13, 24, 14..etc.

If the comparison of the results of your test match very closely than relationship may be assumed. The closer the match the more definite is the relationship. When 2 people match it can be said that they are related to a "Most Recent Common Ancestor" (MRCA). The test cannot tell you who that ancestor is nor when that ancestor lived.

However some additional information can be computed using probability theory. For instance, with a 25 for 25 match it is said that there is a 61% probability that your MRCA is within 5 generations which is within 100-125 years. Alternatively, there is an 83% probability that your MRCA is within 10 generations, which is 200-250 years.

The first column in the top row is "Haplotype". This is the designation you are given based on the complete set of your results on whatever markers were tested. The most common haplotype in Europe is called the Atlantic Modal Haplotype (AMH), because it is frequently found in countries near the Atlantic Ocean.

The haplotype R1B1 is described in Trace Your Roots With DNA by Megan Smolenyak Smolenyak and Ann Turner, Rodale, 2004. "Haplogroup R1B is the most common haplogroup in European populations. It is believed to have expanded throughout Europe as humans recolonized after the last glacial maximum 10 thousand to 12 thousand years ago." This lineage also contains the Atantic Modal Haplotype.

BREAKING NEWS!

We now have results from fourteen (15) previously unrelated participants that indicate that they are related to a common Land ancestor. These results show that James Land, NC, 1793; Joseph Land, VA, 1724; William Land, SC, 1795; Jacob Land,1809, SC; Isaac Land, NC, 1750; Thomas James Land c. 1727-1734 VA; and Samuel Land, Delaware are all from the same family! This shows the value of using DNA testing (genetic genealogy) to break through ancestral brick walls. With their common relationship now established, the hope is that these 11 Land descendants will work together to identify that common ancestor. Stay tuned for further developments.
