Peter:

I agree with Doug McDonald who advised you to bite the bullet and fork out the money for a 37 marker test from FTDNA www.familytreedna.com . I was also tested by OA two years ago and soon learned that 10 Y-STR markers is insufficient to either answer questions about my kinship to others with the same surname; or to give me an indication as to my haplogroup to learn about possible ancient Viking or other connections. If you go the FTDNA route, the first 12 markers will arrive on your personal webpage (before the other 25) along with a comparison of your haplotype to a world wide database that has been SNP tested and placed in one of the categories we discuss here all the time (e.g., R1a1 which is defined by a Y chromosome marker known as M17) and which in your case is bound to provide very interesting information. For the present you could try plugging your numbers into Whit Athey's haplogroup predictor https://home.comcast.net/~whitathey/predictorinstr.htm and see what yo!
ur most likely haplogroup might be. Knowing your haplogroup opens the door to learning the ancient history of your Y chromosome (literally its geographical travels in time back to mother Africa).
