It is difficult to try coming up with a reasonable guess for your final terminal haplogroup with just 12 markers tested. The haplogroups you listed are all part of haplogroup R1b but are all very ancient - not within a recent genealogical timeframe. L21 is downstream from M269, more recent, but still very ancient and not within any meaningful genealogical timeframe.
FTDNA is still in the process of straightening out terminal SNP definitions after the introduction of its Big Y test, and the process is still not complete.
12 markers is not usually sufficient testing for finding recent relatives. Upgrading your results and extending your marker definition out to the maximum 111 markers will not absolutely guarantee that there will be matches waiting for you at 111 but will greatly help you filter out meaningless matches at lower marker resolution.
Hope that helps. And by the way, feel free to post a pedigree in the pedigree thread and we can move your pedigree over into the patriarchs page.http://www.worldfamilies.net/forum/index.php?topic=4524.0
