I was reading the dna ancestry project site and came across this article
http://www.dnaancestryproject.com/sp_case_study.php?is_special=c3ViLWFuY2VzdHJ5
This intrigued me:
"By comparing your haploytype to other males with your surname, you will be able to piece together the puzzle of your global family network. Because your haploytpe is passed down to you from your ancient forefathers, all males who share the same lineage as you, even if it is very distant, will have the same haplotype as yourself. Using this powerful information, you can conclusively determine whether a family line with your same surname shares a common ancestor with you"
My husband's 7x Great Grandfather was illegitimate and given his mother's surname in around 1700. If we did the DNA test through ancestry, and his 'haplotype' matched someone else who's done it, might we be able to conclusively say what that original surname was? Or is it not that clear-cut?
What are people's general thoughts on this method of genealogy?
Thanks
Erin

My take on the DNA thing (and I could be wrong) is that it is not going to say you are decended from surname *A*, but rather it will say if perhaps your hubby and the man next door (only an example of course lol) share a common ancestor somewhere down the line.

It may be mildly interesting to be tested, but it's not terribly informative as yet. The test will show that your DNA 'markers' are those for eg western Europe, Africa, far east but that's about it. It may show that you have markers similar to those of only some other members of the 'ABC' family - & so prove that the 'ABC's aren't all related. It may be an intersting project to be involved it but it won't give very much specific information- especially if you're going back 7 generations

Hi,
The tests are becoming more informative all the time as this is a relatively new science.
For example two years ago I had my YDNA tested and found I was a common old garden R1b, which means that broadly speaking I have the commonest DNA type in Western Europe. No real surprises there as the vast majority of my ancestors were English, with only a handful of Welsh/French/Dutch/Belgians/Italians.
Recent discoveries have enabled R1b to be split up into different branches. I have now found that I am what is known as L21+ (or R1b1b2a1b5 or R1b1b2a1a2f). L21+ is a branch of R1b which only occurred about 4500 years ago, so everyone who is L21+ is related from c.2500 B.C. i.e. from the Bronze Age. However, most L21s actually seem to be related within a much smaller timeframe, say, the last 2500 years i.e., since the Iron Age. This is the period in which many people think Britain's population started to greatly expand.
Now my paternal surname is Harris, which I have only traced back to c1800 in West Oxfordshire, although I am fairly confident it is related to other Harris families in the same area back to the late 1600s. On the face of it as it is such a common surname my family could have come from just about anywere in the UK before the 1600s. Luckily another benefit of DNA testing is it allows you to find pre-surname relatives and in my case this provides some compelling, although not definitive, evidence that my family were still in the W.Oxfordshire area c.1000. After comparing my DNA with some of my other L21+ cousins I found that the person most closely related to me was someone called Coberley who came from Coberley in Gloucestershire. Coberley is only about 20 miles away from the place my Harris ancestor lived in 1800 and the Coberley family originated there in the 1200s or maybe before. So my Harris family shared a common paternal ancestor with the Coberley family probably just before surnames were adopted and near the Oxon/Glocs border.
I am also more closely related to some Scandinavian and German L21s than to most British ones. This suggests our common ancestor was involved in some of the European migrations, possibly in the roman/saxon/viking times.
So, a picture is emerging of the path my ancestors took thanks to both paper records and DNA. I am sure that within a year or two new discoveries will be made and L21+ will be further subdivided. This will enable a much clearer picture of when and where my ancestors lived. Sooo, watch this space.
In the meantime I would recommend looking into getting a deep-clade Haplogroup test. Details of the main British haplogroups can be found on:-

Yes, I totally agree. With such a tiny percentage of the world's population actually on a database, you shouldn't expect anything very specific, unless you are very lucky.

Someone in one of my lines set about getting DNA from the males of that surname and the results are quite interesting in that they show how various families we believed connected are clustered in different parts of England.
There were quite a number of participants and it wasn't cheap- $150 US per swab.
The organiser of it all was a scientist and he was pleased with the results. Maybe in my next life when i have time I'll get down to mastering iit all.

Yes, that's great if you want to go back 15,000 years, but I doubt whether anyone had surnames back then. I would be grateful to go back more than 200 years with parts of my family tree, and with the very small numbers of people on DNA databases, the chances of DNA being of any use to me are very slim indeed.

Your family have been around for millions of years so the time when they have been using surnames is only an extremely small part of your history! It depends on what you are interested in I guess; the DNA Haplogroups I was talking about reveal things about your pre-surname history, not whether X was the son of Y or Z.
Yes of course my ancestors go back millions of years - if they didn't, I would not be here ! Most of us like to know quite definitively who our forefathers were, and names and dates on paper are all we have. Prehistoric DNA will give me neither. Yes, one day I may pay to find out where my "tribe" came from, but I don't really think that's part of my current quest.
Also, in such a tiny island (the UK), there will have been much interbreeding over the years (it's a mathmatical certainty), so many of us will have shared DNA anyway.
