 International Lindsay Surname Haplotype Database

The composite DNA marker data, for the current 155 participants in the International Lindsay Surname DNA Project, can be viewed by clicking on Composite Project Haplotype Data.

This October 4, 2007 update to the content of the International Lindsay Surname Haplotype Database includes the following changes.

(1) the addition of twenty-four (24) new participants, L0132 thru L0156 (less L0155).

The International Lindsay Surname Haplotype Database spreadsheet is composed of the original 26 Y-chromosome STR markers (markers 1 thru 26)  The database also includes the additional 17 markers (markers 27 thru 43) as a result of the high-resolution 43-marker upgrade test.  The order in which the 43 markers are listed in the spreadsheet will remain as seen since some of our earlier project participants may not choose to test for the expanded 43 markers.

Markers number 44 and 45 have been added to the chart in the rare instance when marker DYS464 has six allele values instead of the usual four allele values (see DNA Group 7).

For the time being, I will continue to use the original 26 markers, for the purpose of comparing individual DNA profiles, for placement in one of the established DNA Groupings (1-15).  According to the current guidelines, a participant must match another participant with three or less (out of 26 markers), one-step, marker mismatches, in order to be declared as having the potential of sharing a common ancestor within the time frame whereby surnames had become common practice.  If the comparison is based on the 43 markers, the grouping will be determined by participants with four or less marker mismatches.

This database spreadsheet will be updated as additional Lindsay participants are tested.

If you believe your specific Lindsay/Lindsey genealogical lineage intersects with one or more of the lineages that make up a particular DNA Grouping (1 thru 15), then your DNA haplotype/profile should be a close match (three or fewer mismatches) with these participants.

There is only one way to confirm your DNA relationship with the other Lindsays/Lindseys in this database.  Click here to  Sign up today to be DNA tested !

To view the genealogical analysis and conclusion statements based on the DNA data found in this database, click on the individual DNA Groups 1 thru 15, that have been developed thus far from the testing and analysis, and found in the navigation bar in the upper left of this screen.

Refer to the Merged R1b DNA Groups, found near the bottom of the navigation bar in the upper left of this screen, to see the merged DNA Groupings that is composed of all the R1b haplogroup participants.
