Those are correct. List updated. Dexter Myles appears in the comics as the owner of the Flash Museum. Lydia Lockwood was the wife of Agent Liberty. While Hedy Lamarr is largely known as an actress, her skills as an inventor laid the foundation for modern day wiFi technology. Earth-2 Henry Hewitt was a much nicer version of Tokamak, found just a few days day. Nyxly was the main villain in the final season of Supergirl. Cassandra Austen's accomplishments as a watercolourist were a bit overshadowed by her sister Jane's writing career. Sargon was a Golden Age superhero, though for the fast few decades he's sometimes been depcted as a villain. Henry Stein was an ancestor of Martin Stein. Natalie Lane Irons is the daughter of Steel. Despite the in-show connection to Elvis, I wasn't able to find any evidence that Lucious Presley really existed. I decided to treat the Pre-Crisis Jonathan Kent (Jr.) as a separate character from the Post-Crisis version because the Pre-Crisis version was an infant while the Post-Crisis version, seen just over a year later is a teen. Normally I don't make note of Earth-38 (it's Supergirl's Earth, thus a default Earth), but an Earth-1 character with the same surname/no first name has also been seen. In the comics Xotar is male and is the Weapons Master.
