My choice would be
Helena Guinevere. It fits the Arthurian romance theme, but
Guinevere as a first name seems a bit too obvious and more out there than
Lionel and
Tristan.
Helena, on the other hand, fits nicely, and
Guinevere can stay in the middle.
Emily Jane is nice but very average and doesn't really go with
Lionel Arthur and
Tristan Micah.
LISTEN TO THE MUSTN'TS
-
Shel Silverstein
Listen to the MUSTN'TS, child,
Listen to the DON'TS
Listen to the SHOULDN'TS
The IMPOSSIBLES, the WON'TS
Listen to the NEVER HAVES
Then listen close to me—
Anything can happen, child,
ANYTHING can be.
