I thought you might be interested in finding out your predicted subclade - which would help you to identify your clan more narrowly in time and place. To do this, just use the easy, free Cullen predictor at http://members.bex.net/jtcullen515/haplotest.htm Sometimes it can predict your subclade more specifically than the currently available deep clade SNP test. If you want, you can confirm your prediction later with a deep clade test. This is now particularly useful with certain haplogroups such as I and R and will be expanded soon to include more detail on other subclades.
Once you know your subclade from the predictor, you can research what it means from time to time as new data is developed to define it more specifically. You can google your subclade and look it up on Eupedia at http://www.eupedia.com/europe/origins_haplogroups_europe.shtml#J
You can also find out more by joining your subclade or haplogroup project (free), such as R1b, I1, I2a, or G2a group or the closest they have to your most specific haplogroup or subclade. Use the "Join Projects" button on your testkit page. Remember that we all benefit by having our Key markers out in front when the researchers are trying to figure out which subclades come from where and when.

Derivation of Key Surname
The variations of the Key (and variants) surname likely evolved in different ways and at different times and places for different and sometimes completely unrelated Key family lines during the era when surnames generally were coming into use.
