FTDNA should list the changes someplace. I have one E1b1a result with 37 markers. No changes noted there. Still have no database matches on any level, not even 12 markers - and only a handful of RAO matches at 10/12 (9/12 & 8/12 are there too) - but I don't think any of those should be considered significant. I figure if we ever get a match, definitely will be kin to my maternal Gram's Dad's line.
