Aberdeenshire Jam?sons STR - Results

The Y-DNA "PROFILE" - As Expressed in Numbers - The STR Results

Y-DNA test results are usually expressed as a string of DYS[1] numbers, collectively known as STR[2] numbers and often referred to as markers.[3] These numbers are not medically informative, personally identifiable, or even understandable to the scientifically untrained, nor need they be.

DNA genealogy might be better understood and easier to use, if this collection of numbers are simply thought of as that person's YDNA profile.

It is then just a simple matter of comparing one person's profile with another person's profile to determine if they are related. Where more than one persons YDNA profile matches others, that profile can be said to be a "family" YDNA profile, which in the case of our particular Jameson family can be seen below. If the profiles do not match, it can equally be said that these two people are not related, at least not biologically. Questions arise where the profiles are close with just a few differences, but even two or three mismatches, over a 37 marker profile, can mean hundreds of years of separation to a common ancestor, and not generally considered a direct line of closely related people.

Below are the STR results of those Jam?sons Y-DNA tested, we know of from the Aberdeenshire and North East area of Scotland. Each row below represents a single Y-DNA test result. Please note: the meaning or significance of these individual numbers are not as important as is it's representation as a "profile," thereby established for that entire particular family, when comparing to other family tests.

Shown above are the results (line by line) of the various Y-DNA tests from Jam?son families known to be from the North East area of Scotland. We have located similar tests as close to each other as we can to help visualize similarities and allow for analysis as to possible relationships..

Beyond just our use of these "Aberdeenshire" YDNA project collection of YDNA tests, is that the Y-DNA profile from any living male, worldwide, can now be compared to other established Jam?son Y-DNA family profiles and if anyone matches any other profile (test), they can be said to be of a common ancestor, regardless of name, place or otherwise known ancestry. Furthermore, if one of these people can otherwise identify and prove an ancestry (any ancestry), past a common ancestor, then those matching test can both assume that same ancestry. Conversely, if a Jam?son male has Y-DNA profile does not match a different test (family profile), he cannot claim to be part of that other family, at least not genetically, regardless of any paper trail.

SAME PROFILE - Different Surname?

Yes, this is not just possible, it exists, and there are several known examples. Surnames are relatively new and our Jam?son ancestors were part of a family that existed before surnames were used. Anyone descended from our common ancestors, prior to the use of surnames would, of course, match our same DNA profile. Others, of irregular birth, or those that adopted alternate surnames would also match our DNA profile. We were all, at onetime, descended from the same family. See here for a more thorough explanation: Same Y-DNA Profile, But Different Surname?

However, for our purposes, to determining the history, ancestry and complete content of our particular "Jam?son" family, we focus primarily on those using the Jam?on surname.

OUR HAPLOGROUPS - Ancient Historical Profile

In addition to the (above) DYS part of Y-DNA, all male humans alive today can be classified into a specific Y-DNA Haplogroup in the Y-DNA Haplotree based on SNP markers found in their Y-DNA. By examining SNPs from indigenous individuals from around the world, scientists can estimate the time and location each SNP first occurred. Once the time and location of occurrence of the SNP is known, it becomes a "time and date stamp" which can be used to trace ancestry.

Haplogroup results for our Aberdeenshire Y-DNA study are separate and different from the DYS results above and can be found elsewhere using the following link.

ALSO - There is a menu choice here to compare any combination of DYS test results, not limited to any particular family combination. Give it a try.

In the last few years DNA testing for use with researching family histories and genealogy, has become widely available, affordable and as such a unique and important toot. There are now several very reputable labs who do this specifically for genealogy as well as groups who have organized for unique family projects.

We test for the Y Chromosome and use the Family Tree DNA - Genealogy by Genetics, Ltd. company. This type of DNA testing helps us understand and focus on the patriarchal nature and family groupings for our Jam?son families of Aberdeenshire and the North East area of Scotland project. 

We urge every Jam?son male descendant (must have the Jam?son surname) to help find your own ancestors with this DNA program. Please contact us if you have any questions, or about how to coordinate your results within our project.
