Did you only run the Human generator? Do any of those names correspond to the major Forgotten Realms ethnicities? The surnames say Chondathan or Tethyrian, but the given names are all over the place and then some. And sorry, but Bemaald Cloudsoul is not a Lizardfolk name.
Are you aware of a book on Faerun languages to English translations that the rest of aren't?
Honestly I wasn't really that concerned with tying them to a particular ethnicity, just that they sounded like fun fantasy names. I just used the blood elf generator because if we are honest 99% of people won't notice or care. If you want names more fitting to FR ethnicities, that can be done too.
