How lucky can you get?

Genetic genealogy, aka using DNA testing to (dis)prove theories and relationships between family trees, can be the luck of the draw.

Does anyone actually still exist that would be eligible for the appropriate test?
Has anyone with the right surname and genes tested yet?
Were the any mishaps down the generations between the shared ancestors?

You may recall the story of what happened when I voted at our local body elections a year or two back.

There is now a sequel.

Since then John has been back to England and met up with some of his newfound maternal grandmother's relations, but the GOVIER connection was still unproven/unsolved.  Was he actually a GOVIER by descent or in name only?

DNA testing, and a match to a GOVIER descendant of the Pitminster (Somerset) GOVIERs would be a great start to confirming that his step-grandfather was his actual grandfather despite the grandparents marrying in the year following his father's birth..

Along came a suitable price reduction in the entry level test for Y-DNA. This was enough for John to venture forth, with a bit of prompting. We had even found a couple of potential candidates from the Pitminster line to contact if necessary.

He was cautioned that at 12 markers it was more likely that he would get a number of matches from a variety of surnames, and that it really was only the start of the process, unlikely to be at all definitive given that such matches share an ancestor hundreds, if not thousands of years ago, rather than within genealogical time frames.

The Y-DNA12 results arrived today.
How many matches - one.
Surname - his.
Most distant ancestor - the same William GOVIER of Pitminster Somerset.

I'm not sure I want to suggest further testing and see this match fade away as the markers increase!
