Familytreedna.com and can download the data from it. My problem is how to represent/integrate that on my own website, apart from a pdf. I'm wondering if anyone has come across another family clan website who have figured out how to do this.

opportunity there for some enterprising developer ! Family history is big business.

part of some tribe ( just a wee 1 percent) in Siberia. I didn't even know what they were and had to look it up lol

those I call gatekeepers, because if you can find one previously unknown to you, they can sometimes unlock many new lines of the extended family. Because my great great grandmother was from a Protestant Anglo Norman Irish family, it unlocked thousands (going back to Kings of England, Ireland, France etc), whereas my wife's line only has records back to the 1830s.

so I've got that going for me *grin*

I know what my Ancestry DNA test results look like, but you question is vague enough that I can't figure out what you are asking...

Geographical is so obviously a map, that I doubt that's what you mean. Links to related people is a family tree, with some sort of designation that the individuals have taken a DNA test. Since the sites (Ancestry, 23 & Me, etc.) don't talk to one another, a mix of results from differing sites would be meaningless.

I can't think what else might be meant by "DNA data" other than the raw data which, as far as I know, they don't provide.

DNA tests to verify what branch of the family line people are from.

For example, on my mother's line, she is descended from two groups who settled in a particular county in Ireland, while the majority were further North.

I'm now in touch with the project leader of my paternal name, and have asked for her input, so I'll report back here once they respond.

DNA results have no clue what branch of your tree they are from. They can be compared to other individuals, and their tree and yours can be compared to see how you are related, if both trees go back far enough to contain common ancestors. But there is no way to say that a particular stretch of DNA is from your mother's father's line.

The only thing that can be done is to determine that these two people are likely related, and then it's digging through their trees to find the common ancestors. My results show me thousands of people who I am related to, but since they have no tree linked to their results, I'll likely never know HOW I am related to them.

Being able to show how two people are related already exists in many family tree programs, but you have to pick the two people.
