I think I discovered a possible reason why you are not having any matches. Your surname (Wilson) is obviously an English surname (son of William) but your deep ancestry suggests a different origin. In 2011, you haplogroup has been renamed to I2a2a and FTDNA will eventually update their haplotree. Here is a geographic origin of your haplogroup (from a Wiki):
I2a2a-M223 (L34/S151, L36/S152, L59, L368, M223, P219/S24, P220/S119, P221/S120, P222/U250/S118, P223/S117) (Former I2b1 in the Y2010 tree) Occurs at a moderate frequency among populations of Northwest Europe, with a peak frequency in the region of Lower Saxony in central Germany; minor offshoots appear in Moldavia and Russia (especially around Vladimir, Ryazan, Nizhny Novgorod, and the Republic of Moldavia).
This description does not imply very much of this haplogroup ended up in England. I would recommend testing for downstream SNPs of M223 to get a more accurate location of the geographic origins of your genetic line.
This disconnect suggests one of two scenarios: 1) your DNA is quite rare for England since most of your genetic relatives lived elsewhere; 2) your ancestry could include a NPE event (adoption, name change, etc.), so you should be on the lookout for this scenario. In either case, you are unlikely to have many matches of your English surname with a deep ancestry that is dominated by German and Moldavian geographies. The bad news - you will get few random submissions that will match yours. The good news, since you have a unique Wilson DNA fingerprint - you will be able to build your well defined cluster based on DNA if you are proactive in getting good candidates to test.
