Here are my thoughts

Boy:
Landon - not a fan
Bastion - maybe shortened from Sebastion but not as a name by itself
Dallas - dodgy 80's tv show here too
Teirnan/Tynan (pronounced Tar-nan) - would never have thought to pronounce it that way so a bit confusing
Luka - I love it
Blair - I love it

Girl:
Lacey - yep
Avalon/Ava - yep beautiful
Dot - very much a nickname or kids name, can't see this as being the name of a successful woman in her 30's
Abernathy/Abbie - nice
Blair - I love it
