Friday Surname Haplotype Database

Last Update of This Database: May 2005, with Round 1 testing additions.

The table format shown below is used to report the DNA results of the current level of participation in the Fridig  Surname DNA Project.

The May 2005 update to the content of the Fridig  Surname Haplotype Database included the following changes. 


The Friday Surname Haplotype Database is composed of Y-chromosome STR loci/marker systems values for individual Friday (how ever spelled) male participants that were tested at various times for the Y-chromosome markers indicated.  This database will be updated as additional Friday  participants are tested.

Table Notes:

  1. The first column, on the left of the table, is a Friday  Code Number that is simply an L# that was arbitrarily assigned to each participant by the Project Coordinator to establish confidentiality.

  2. The second column is the last four significant digits of the Laboratory Control Number, assigned to this sample by the laboratory at the start of the test cycle.

  3. The Surname column is the actual Friday (how ever spelled) surname of the participant.

  4. The DNA Group Number column provides a grouping of participants based on a maximum of three DNA marker mismatches between these participants.

  5. The Test Round # column simply designates in which Round of Testing this particular participant came into the database.

  6. The next 26 columns, marked 1-26 near the top of the table, represent the various loci where the STR (Short Tandem Repeat) allele values were measured. The standardized published DYS numbers and other nomenclature for a particular locus are also listed.

  7. The last column is simply a duplication of the L# codes placed on the right of the screen to help correlate the individual DNA profiles from left to right.

  8. Near the bottom of the table is a line designated "Range of Variants".  This line represents the range of repeat values found among the current participants in the database.

  9. The last horizontal line of the table measures the number of different variants or marker values found among the current group of participants.  The diversity found among the various markers is important in order to differentiate between different surnames as well as the various Fridig  lineages spread around the world.  For the Fridig DNA Project, marker YCAII-b provides the most diversity with seven (7) different marker values found among our current group of participants, followed closely by markers DYS385a, DYS385b and DYS389II with six (6) different values for each.  Markers DYS391, DYS426 and DYS454 (two values each) serve a purpose but have provided the least amount of diversity up to this point in our testing.

DNA Grouping

For comparison purposes, the current Fridig Surname DNA Project participants have been divided into categories (DNA Group 1 through DNA Group 9) where appropriate, with the balance of those participants who do not currently match at the end of the tableThese DNA Groups will contain all the participants who have matches which indicate they have a “near term” Most Recent Common Ancestor (MRCA).  Each DNA Group will be composed of two or more people who have no more than three marker mismatches.

The "earliest known ancestor" will also be provided for each of the participants in these nine unique DNA Groups to assist in developing the Most Recent Common Ancestor (MRCA) for each of these groupings.  The "earliest known ancestor" should not be confused with the "earliest proven ancestor".  It is the hopes of the Fridig  Surname DNA Project that one day soon our participants will fully document their genealogies and we will be able to use the "earliest proven ancestor" term with confidence.

To really be meaningful, those participants in the database who have not been grouped due to having more than three (3) mismatches with the other participants will need to wait until the Fridig  Surname Haplotype Database grows with the addition of more Friday males from which hopefully we will find other FRIDAY lineages that provides fewer mismatches for their haplotype, yielding a potential common ancestor in the nearer term.

To view the analysis and conclusion statements based on the data found in this database click on the various DNA Groups 1 thru 9, that have been developed thus far from the testing and analysis, and found at the navigation bar in the upper left of this screen.  There is also some additional general analysis & conclusions found at the  General Conclusions page.
