I am conducting a Haldane DNA study that might shed some light on your family. It won't give names, but it might find some relatives or at the least, the migration pattern of your ancestors from thousands of years ago.

The Haldane DNA Project now has six participants: John, Don, Ian, and David Haldane, Ted Haldan, and Don Hadden. This report is on the results of their DNA findings. John and Ian have a proven (by paper trail) common ancestor in Adam Haldane, born 1746 in Longniddry, East Lothian, Scotland.

Don's family can be traced to George Ward Haldane, born before 1838. His place of birth is unknown, but his children were born in Durham County, England. There is no paper trail connection between Ian's and John's family and Don's family or Ted's family or Don Hadden's family.

The DNA is tested in three stages: the 12-marker test, the 25 marker test, and the 37 marker test. Each subsequent test supersedes the prior one and provides greater detail about the genetic history of the person being tested. Imagine the 12 marker test to be like viewing a beautiful landmark from several miles away - you can see it and observes general things about it. The 25 and 37 marker tests bring you closer and enable you to see much greater detail. We strongly recommend the 37 marker or greater.

There are many, many different groupings of like-DNA in the world. Each can be traced to points of origin in Africa some 35,000 years ago or more. Many of the groups have common beginnings, but have split into distinct measurements. These groupings are called HAPLOGROUPS. Each Haplogroup is a distinct "family" of DNA. Some can be traced to certain places in the world in past history.

This DNA study is exclusively on the male Y-chromosome. Women do not have a Y-chromosome. Therefore, the data examined on the Y-chromosome of the study participants has been passed down through the generations from father to son. Since surnames (Haldane in our case) have also been passed from father to son, the correlation between these DNA tests and surname history is statistically pretty high (although certainly not absolute, as surnames have changed over the years - Haldane has been spelled Hadden, Halden, and many other variations).


The DNA tests of the participants reveal a lot of answers and many questions as well.

John and Ian are a part of Haplogroup I1c (the letter after H). Don Haldane and David Haldane's Haplogroup is identified as R1b1. Ted Haldane and Don Hadden belong to Haplogroup R1B1c. These Haplogroups make up more than 80% of the Haplogroups in all of the United Kingdom, with R1b consisting of more than 50% and Haplogroup I making up about one-third of the total. As to placement in other parts of the world, R1b shows origins and the strongest presence in Spain and France while the Haplogroup I is very widespread with a very strong presence in both Scandinavia and Greece. R1b makes up over 85% of the DNA at the Spain/France border area, more than two-thirds of the DNA in Portugal, and more than half in Germany. Haplogroup I does not show that level of dominance anywhere, although it is more than one-third of the DNA in Sweden, almost half in Norway, and almost half in Greece. It also shows more than 40% in Afghanistan.

The fact that Don's, Ted's, David's and Don (Hadden's) group (R1b1) is different from Ian's and John's group (I), is significant. It proves beyond any doubt that they do not share a common ancestor in the last 30,000 years - long before surnames were a part of human history. Therefore, we have already proven that there is more than one origin of the family name, Haldane.

It is also significant that even though they share the same last name (Haldane) and the same Haplogroup (R1b1), Don and Dave vary by 19 of 37 markers. This means they are certainly not related. Dave varies from Both Don Hadden and Ted Haldan by 16 of 37 markers, also a sure sign they are not related. So Dave Haldane is not related to any of the five preceding people who tested!
