Several are real names, if very weird to choose for a kid and/or slightly misspelled. Like Seneca, Samara (which is both a name and a city/region of Russia), I've personally known a Lyra (second worst person I've ever known, and the brainwormed truscum former admin of a certain notable trans discord server), and Elsey is definitely a historically attested name (even if spelling it "Elsie" is more common AFAIK). "Roxi" seems to be a cliched stripper name turning into an actual name. Apparently "Rodi" is just an Italian name, derived from the island of Rhodes.
