Family tree
A family tree was visual representation used in genealogy to graph an individual's familial connections.

Among the Akaali, lalogi orbs held significant value to a family, representing a family's history by including their holographic likeness on the branches of an actual representation of a tree. ()

Counselor Deanna Troi researched the family tree of Clare Raymond in late 2364. ()

In 3190, Michael Burnham returned a lalogi orb to Patri Doxica, inspiring her to create her own version of a family tree including Spock, Sarek, Mike Burnham, Gabrielle Burnham, Saru, and others. Cleveland Booker noted upon seeing the tree that, although frustrated over 's birthday, Booker wasn't including him on any family trees. Burnham's tree later inspired Zora to create something similar for herself of the  crew. ()
