Ken,

The contact person listed for 9EUBC is a Joel Sinor, so I'm assuming it's his sample and that he's the one who reported that he was "H1a(tested)." I realize it's possible that he is mistaking an estimate made by FTDNA for a test result, and the best way to determine this would be just to ask him. But even if it turns out that what he's reporting is just an estimate, I think this still makes my point about the importance of SNP testing; if we can match so closely and have our estimated haplogroups so far apart, how much confidence can we have in those estimates?

Who said 9EUBC was SNP tested as H1a?
