While not written or filmed until well after the completion of Star Trek: The Next Generation: The Best of Both Worlds: Part 2 (1990), "Family," popular in its own right, has come to be seen as the third part of "The Best of Both Worlds" serial. It is one of the few times where characters' families are introduced (Worf's parents, Picard's family). Although the relaxed, peaceful, episode feels like a 180-degree opposition to the adventurous, warlike serial, part of its point is to put in context what the Borg were threatening - loved ones, as well as civilization and planets.
"Family" not only revealed personal information about the series regulars, but Chief O'Brien also gained a full name, Miles Edward O'Brien, as well as a more defined rank, Chief petty officer, though his rank insignia would continue to change throughout the series. In this one he wears two irregularly-shaped pips.
Paramount expressed initial concern over the casting of Theodore Bikel and Georgia Brown, feeling that the two, who were best known for work in Yiddish theatre, would be too comedic or stereotypical for the parts.
Michael Piller suggested the script be given a science fiction oriented subplot to round out the episode, though none of the proposed story lines met with anyone's satisfaction. One proposed storyline would come to be expanded on, and serve as the plot of Star Trek: The Next Generation: Remember Me (1990).
David Birkin delivers the line, "someday I'm going to be a Starship Captain." This is likely a coincidental foreshadowing in this 1990 episode, but it could have been an intentional Easter egg by the writers as the same actor returns in Season 6, Episode 7 "Rascals" (1992) to play a 12 year-old version of Capt. Picard who gives a few orders as captain before ceding command to Riker.
Jack Crusher appears in the hologram wearing a Starfleet uniform from the TOS films but without the undershirt that had trapunto collar and cuffs and with a Star Trek: The Next Generation (1987)-era com-badge.
