International Lindsay DNA Group 4

"Lindsays of Sevier County, TN & Laclede County, MO"

In an attempt to establish a basic geography for this group of Lindsays/Lindseys, DNA Group 4 will be referred to as the "Lindsays of Sevier County, TN & Laclede County, MO" until revised.

After the expanded 43 marker results, participants L0003 and L0017 have been removed from DNA Group 4 since they exceed the maximum of four mismatches out of 43 markers with any of the current Project participants.

DNA Group 4 is now composed of six (6) participants.

Click on DNA Data Spreadsheet to see the DNA marker values for the current participants of DNA Group 4.

The first two participants (L0037 & L0067) in DNA Group 4 are a perfect match on the original 26 markers).  It would be interesting to see how they match on the full 43 markers since their earliest known ancestors came from the same geography, that being Sevier County, Tennessee.

Participants #L0022 and #L0027 follow with only one, one-step mismatch, out of the original 26 markers, with the first two participants in the table.

The name of the Most Recent Common Ancestor (MRCA) for these Lindsay/Lindsey lineages has not yet been proven, but the stated pedigrees of participants L0022, L0027 and L0037 of DNA Group 4 would suggest James Lindsey (b.1799 TN?/NC?) as their MRCA.

If you have information, accompanied by the appropriate citations, that demonstrate how these Lindsay/ Lindsey lineages of DNA Group 4 are connected, please contact Ron Lindsay

Reference Notes

1. Proper Analysis of DYS389-1 & DYS389-2 Marker Mutations.

In analyzing the marker values in the table representing this DNA Group, it is important to remember the following in your analysis of loci DYS389-1 and DYS389-2 matches and mismatches.

1. The loci DYS389-1 and DYS389-2 are two legitimate lengths of DNA but move in tandem.
2. DYS389-1 refers to the length of only one portion of the DYS389 marker.
3. DYS389-2 refers to the total length of the DYS389 marker. Therefore, when there is a one step mutation at DYS389-1, it will also appear to be in DYS389-2.
4. When comparing one individual to another, if the values for two individuals differ by one repeat at DYS389-1, that represents a one-step mismatch.
5. If the values for the same two individuals differ also by one repeat at DYS389-2, then it should only be counted as one combined mutation for DYS389-1 & DYS389-2.
6. If the marker values for two individuals differ by one repeat mismatch at DYS389-1 and a two repeat mismatch at DYS389-2, then it should be counted as two separate mismatches or mutations.
7. There is another and potentially even more confusing situation that could occur at marker DYS389. If the marker values for two individuals differ by one repeat mismatch at DYS389-1 and then a perfect match at DYS389-2 for these same two individuals. This should be counted as two separate marker mismatches since the value mismatch at DYS389-1 was offset by a mutation in the opposite "direction" from the value found at DYS389-2 and appears to cancel out the mutation that occurred at DYS389-1.
8. However, keep in mind there can be a mutation at DYS389-2 that will not affect the length found at DYS389-1.

Note from the Project Coordinator:  It is believed that John W. Lindsay (1825-1914) and Evan Martin Lindsey (1837-1909) are brothers and the sons of James Lindsey (b.1799 TN?/NC?) who married Nancy Pate.  If this is true, the Most Recent Common Ancestor (MRCA) for participants L0022 and L0027 is James Lindsay, born 1799 in either Tennessee or North Carolina.

Note from the Project Coordinator:  Participants L0022 and L0037 both claim descent from the same "Earliest Known Progenitor"(John W. & John William Lindsay).  Thus, if the stated pedigrees can be proven for participants L0022, L0027 and L0037 of DNA Group 4, then we could conclude that John William Lindsay (1824-1914) is the MRCA for participants L0022 & L0037 and furthermore the father of John William Lindsay and Evan Martin Lindsey, believed to be James Lindsey (b.1799 TN?/NC?), will become the MRCA for participants L0022, L0027 and L0037.
