International Lindsay DNA Group 2

In an attempt to establish a basic geography for this composite group of Lindseys, DNA Group 2 will be henceforth referred to as the "Lindseys of Long Marsh, Frederick County, Virginia" until revised.

Susan Grabek has been designated as the Group Administrator for DNA Group 2 and can be reached via e-mail by clicking on Susan Grabek.  Susan is a very knowledgeable researcher for this grouping of Lindseys and should be your first contact for questions pertaining to DNA Group 2 genealogy and in the determination of the Most Recent Common Ancestor (MRCA).

Susan Grabek has created an external web site specifically for DNA Group 2 genealogical researchers.  Click on Susan's Group 2 Web Site to access.

The DNA Group 2 is currently a grouping of sixteen (16) individuals.

Click on DNA Data Spreadsheet to view the DNA marker values for the current participants of DNA Group 2.

An interesting fact regarding DNA Group 2 is that 100% of the 16 participants currently spell their surname with an "e".

Participants L0029, L0083, L0102 and L0156 are a perfect match out of 43 markers, with the NULL reading for L0029 at marker DYS441 not considered as a mismatch.  These four participants without doubt share a Most Recent Common Ancestor (MRCA) in the very near term past.

It is very likely that L0102 and L0115, with one mismatching marker at DYS388, share a MRCA at Jacob Lindsey who married Elizabeth Abrell.

There appears to be known Hezekiah Lindseys in the ancestry of both participants L0038 and L0083.  Clermont County, Ohio also appears to be the common geography for the ancestry of these two participants.

Participants L0018 and L0102 are a perfect match, out of the original 26 markers, with each having a "Jacob" Lindsey who was born in Georgia in the early 1800s.  It would be very interesting to see how their 43 markers would match up if L0018 would upgrade to 43 markers!

I highly encourage the 6 participants in DNA Group 2 who have not expanded to 43 markers to do so as soon as possible.  The cost is $37.50 USD.  If you wish to proceed with the expanded 43-marker testing, click on Ron Lindsay and send me an e-mail requesting the additional information.

The name of the Most Recent Common Ancestor (MRCA) for any two participants of the DNA Group 2 has not yet been proven, but the participants are currently researching the data and possible merge points.

If you have information, accompanied by the appropriate citations, that demonstrate how any one of these Lindsey lineages in DNA Group 2 are connected, please contact Susan Grabek, Group Administrator, DNA Group 2.

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.
