In his original post Guy Etchells suggested that there may come a day when DNA testing, after much scientific progress, would be really useful to us all and inevitably many posts then followed with stories of knocking down brick walls as the result of a DNA test.
I was probably a very early adopter of the possibilities of knocking down my main paternal brick wall and I took what was then the standard DNA Y chromosome test way back in 2004. My test was actually paid for by the DNA research project into my surname and its derivations hosted by the DNA company. It was by today's standards a fairly limited test and all it succeeded in showing was that I was unrelated within any reasonable timescale to anyone else with the same surname in that project. The project has grown since then and now numbers several hundred people but I am still unrelated to any of them (sadly the original sponsor died many years ago too).
That was a huge disappointment, partly because it failed to knock a single brick out of my wall (which remains standing today 15 years later) but it also meant that I was unable to grab hold of the coat tails of the person who started the project and who had progressed impressively far back along his ancestors. Would that they had been mine too!
The company I used was Family Tree DNA based in the USA and of course their database is dominated by Americans but as far as I know, none of my ancestors ever emigrated to the USA so it is perhaps unsurprising that their database, even today, doesn't include anyone who shares my DNA with the same surname. After several years when I got no 'matches' I corresponded with the company and all of a sudden I started to get 'matches' again and I still get one or two a month, but still no-one who shares my surname. Most such 'matches' seem originally to have come from Ireland, or still live there, but my ancestors are solidly East Midlands, England going back to the mid 1700s. That's where my brick wall stands.
So in summary, DNA testing has been a complete waste of time for me, but I remain open to possibility that at some stage Guy will tell me that the science has now progressed sufficiently for me to have another go. I should be so lucky to still be around by then of course
