Y - DNA MATCHING


There is a saying 'know thy family, know thyself' and I think we would all agree that we are influenced in some way by the folk who have gone before us, but how many of us have explored our DNA?

I have had my Y-DNA taken and the 25 marker result is very interesting. For the 12 marker test I have 2 perfect matches - Rupinder Singh, an Indian in the Punjab, India, and - Thomas C. Stone, a hillbilly from South Dakota, U.S.A. ( I show no disrespect to Thomas but you should see his family photo.) Rupinder and Thomas are very nice people - and both are as confused as me.

From the 25 marker test, I have 2 with a genetic distance of one and 11 with a distance of two ( i.e. 2 mutated genes ) but none with the 'Thompson' name.

A mutation can occur in 2 ways: -

1. After the egg is fertilized and begins to divide a cell can be misplaced, or both parents have a sleeper mutation and the joining activates this mutation.

2. By ultraviolet rays from the Sun.

Generally if you have a similar 2 cell mutation and different surnames, it is possible that you were related back 1,000 years or 40 generations ago. Unfortunately my research does not go back that far.

Now let us go back in history. Man made his presence 60,000 years ago in Africa, and over a 50,000 year period moved north and east through India to Australia and America, also through Russia to North and South America.

In the period, 10,000 to 8,000 years ago, because the ice age was receding, people moved into the Spain / France area and then into England and Scandinavia.

I am a R1a which originated in the Urals ( Black Sea area ) and moved west and must also have moved east to India ( or an army man got lonely in India ).

I think because of the Norse invasions of England in the 10th century, my English 'Thompson' name was born. If you look at the names of people in Yorkshire in the 15th century they were mostly of Norse origins ( e.g. 'Thoreson' could have translated into 'Thompson' and the 'p' could be from an 's' as written then.

If anyone is interested in furthering their DNA history I am willing to help them.
