Our latest Y-DNA results: P210, P212, P213, P214

P210 matches P155, forming new PARKER Family Group 23.
P212 matches PARKER Family Group 7.
P213 matches P29, forming new PARKER Family Group 24.
P214 does not match any of the PARKERs who have test results available.

One-hundred and eighty-five of our PARKERs have received the results of the Y-chromosome DNA test, shown in the table below. With these 185 DNA tests we have identified 86 different PARKER lines. We are a very diverse group genetically, indicating that our surname was adopted many times by people in different locations. Participation by more PARKER males is needed to help us sort the many PARKER lines into family groups.

Sample #'s are used to present the test results without disclosing the identity of the participants. Marker DYS # is the name of a "locus" or specific position on the Y chromosome, such as DYS #390. The numbers in the table for each participant, such as 13 or 24, identify the gene or "allele" found at that locus. These genes are not known to produce any effect in the body; they are short pieces of DNA that can be identified and used to compare portions of the Y-chromosome from different individuals.

In family groups that have 5 or more test results, the first line in the table is the modal haplotype. This is simply the most frequent value for each marker. The modal haplotype is the most likely DNA profile of the ancestor for that line, and is useful for comparing new DNA results.

  Two individuals 'match' when they have the same numbers for all of the DYS markers, as we see for P04, P73, and P100 in Family Group 1. If two people with the surname PARKER match on 24 or 23 of the 25 markers, as we have for P04 and P06, we feel confident they have a common ancestor. A match on 22 of 25 markers decreases our confidence that they share a common ancestor, unless a paper trail can be found, or they share one or more very rare values as occurs in Family Group 13. Matches at 21/25 or less are usually not worth pursuing unless there is other evidence to support a linkage between those two lines.

Y-DNA Haplotypes and Haplogroups

   Your Y-DNA haplotype is the set of numbers for each marker, i.e. DYS 393= 13. Your haplotype will never change, though it may grow larger if you order additional tests that extend your results from 25 to 37 markers.
   Your Y-DNA haplogroup is the assignment to one of the clades such as R1a1 or R1b1b2. Haplogroups assign individuals to a group whose founder or "originator" lived many thousands of years ago. Each haplogroup may include thousands or even millions of men, such as R1b1b2. Your haplogroup may change as new information becomes available and the genetic tree of man is revised to include the new information. You can find much information regarding haplogroups on the internet.
