TIL Galadriel was Elronds mother in law.

Did you make this graphic?

Not unlike many centuries of European history.

also I just found out that Galadhon is the son of Elmo, a third brother of Elwë and Olwë who was never mentioned in the Silmarillion. that makes Celeborn and Galadriel second cousins

edit: just updated the image to show that

You mean family wreath?
