In Batwoman S01E09 aka "Crisis on Infinite Earths: Part Two", we see old Clark Kent (From Smallville) without powers talking to Lois about daughters. Who are these daughters? I only know about one daughter Lara. Is there any hint in any other DC property about those daughters?
In the comic book miniseries Superman: Secret Identity (2004), a non-Kryptonian but slowly becoming Superman Clark Kent has two daughters, Carol and Jane Kent. The girls in their late teens become as powerful as their father. More here: https://superman.fandom.com/wiki/Superman:_Secret_Identity
