Middles for Either Gender

A name with some sterling qualities, most associated with the British currency and silver markets. Sterling has several recent TV associations, with characters Roger Sterling (on Mad Men) and Sterling Archer (on Archer), and actor Sterling K. Brown (on This is Us).

This name of both a grayish-greenish-blue color and a kind of wild duck can be used for both boys and girls.

Many parents seeking a return to more basic values and a simpler lifestyle are turning to such virtuous girls' names as Grace, Faith, and Hope, but the few that can be used for boys as well, such as True, are more often seen as a middle name.

Unusual and beautiful blue green color and name possibility, a la Cerulean.

Straightforward yet romantic, this is one newly minted name with long-term appeal, especially as a middle name. It was used as such for Tea Leoni and David Duchovny's Madelaine, whom they call West. Definitely ambigender, it was chosen by Marley Shelton for her daughter.
