If you are a male Dodson or Dotson with continuous Male Dodson or Dotson lineage from your most distant ancestor, then a Y-DNA test could help establish your heritage.There is a current project with about 70 men who have already participated.If you are interested in testing, good results can be obtained with a 37 marker test, but less expensive tests can be ordered for 12 or 25 markers, or more expensive testing for 67 markers.For more details see:Price for Y-DNA tests
These are grouped as people believed their ancestors to be but also with people matching with their various markers.The more matches, the more likely a recent common ancestor.
Charles County Maryland Based on those that have been tested so far, there are a few people who match with each other who claim descendancy from the Charles County Maryland Dodsons .If those people are closely related, for example three first cousins, there is not much relevancy to their tests.However, on the other hand, if each person can trace his lineage back to a different Dodson from the 1600 or 1700's then this would be good information to prove their lineage.
Richmond County Virginia There are several people who claim descendancy from the Charles Dodson line which originated in Richmond County Virginia.The results show that these people do share a common ancestor.They believe that they have documented their lines back to Charles born around 1650, and their testing could be a 'benchmark' for others who believe they share this line.In other words, if a person is tested and matches with their markers, then that would be a strong suggestion that they are also a descendant and their research is accurate.Descendants of this line are found in many early counties of Virginia. John Dodson of this line was an early settler in Frederick/Shenandoah County, Virginia, but a second Dodson/Dotson line there at the same time does not match.
Pennsylvania/Maryland/Virginia The third American line is identified as "Thomas of Pennsylvania" .There are several men in this group whose DNA shows a common ancestor.There was a Thomas Dodson line in the 1700's in Chester County, PA and it is believed that one or more of this line migrated to Maryland and also to Frederick County Virginia and later into other Pennsylvania counties and other states.There are Dodsons in the Bedford County, PA area in the late 1700's who were from Maryland, probably Frederick or Washington County, Maryland, but four descendants of Richard Dotson, who was born and lived in Frederick/Shenandoah County Virginia, also match this group.We have confirmation of a link back to the Thomas Dodson/Dotson of Chester County for this group with a 100% match on 37 markers for a descendant of Richard Dotson of Virginia with a documented descendant of Thomas of Chester County, Pennsylvania.The other men in this group are very close matches and are likely to share a common ancestor in America.
Talbot County Maryland We have results from one person whose Dodson lineage originates in Talbot county Maryland.His most distant ancestor is Robert who died about 1745 in Talbot County.His results are important because it has been claimed in the past that the Dodsons of Chester County PA and of Talbot County MD descended from two brothers.Recent research and now DNA shows this is not the case.Neither this line, nor any of the other lines appear to have connections in America, and their past connections are quite distant.
Other Matches We have results from a person whose lineage is from a Richard Dotson who was born about 1799 in Virginia and who married Mary Kesler in Greenbrier County (W)VA 7 Feb 1821.This family later migrated to Nicholas County (W)VA.Richard's brother Thomas Dotson, born 1794 in Virginia marred first to Susanna Kesler in Greenbrier County 21 Jun 1817 and second to Margaret Bright Young 17 Jul 1862 in Nicholas County.No parents have been documented for Richard or Thomas, and it appears they are not connected to the above lines, based on DNA.He matches with another Dotson whose line can be traced back to birth in Tennessee with a later migration to North Carolina after the Civil War.Another Dotson line unmatched line with any others can trace his earliest ancestry to Maryland with a migration in the early 1800's to Ohio.
DNA Genealogy Tests - What do they prove or not prove? There are complex DNA tests to solve crimes or establish paternity, but with DNA testing for genealogical purposes, the results will only show the probability of a most recent common ancestor.
People have always had reasons to establish an ancestral lineage whether it was pride or a desire to join organizations such as the Sons of or Daughters of the American Revolution.But it's sad to see how many errors have been made over the years with scanty or no documentation.DNA is now destroying some family myths about their heritage.
There are different types of DNA genealogical tests for both male and females, but the most common testing is the yDNA testing which is done with males who have a continuous MALE lineage from an ancestor with their surname.All males who share a common surname can be tested to show their relationship or non-relationship to an ancestor with that surname or to other males of the same name.In cases of adoption the surname may have changed but the DNA will not.
Since DNA testing only shows probable ancestors or relatives,it does a better job of proving who is NOT your ancestor than who is your ancestor.It does not remove the need for careful research to prove your line.Also, because of the right to privacy, you will only learn of those that match, and only the amount of information that they wish to share with you.
Based on the number of markers tested and the match of those markers, the probability increases, as seen in the chart below, but again DNA does not prove ancestry, it only establishes a relationship to others who have been tested and shows that you and that person probably share a common ancestor at some point in time. With more matches, the odds increase that there was a common ancestor within a certain number of generations, but if you achieve a perfect match on 37 markers, the best you have is a guaranteed match within 400 to 600 years ago!If 2 persons match on 67 of 67 markers, their common ancestor could be more recent. DNA testing can quickly suggest the possibility of relationships, or those you should disregard, but documentation is still the only way to be certain.
