Danni was John and Anne's daughter, right?
Unless Gidget had another sibling they were hiding throughout the series (probably hung out with Chuck Cunningham), if TNG followed any kind of continuity with the original series, then Danni, being Gidget's niece, meant that John and Anne did end up having kids. My question is, did they ever say or imply that much on the show? (I have barely any memories of TNG)
I see on the credits that Danni's character's last name was not Cooper (John and Anne's married name), but hey, Jeff in the '65 series was a Matthews, not a Griffin!
