Oh,
Marlowe is the best!
I love it because of
Christopher Marlowe. Marlow is just another surname, but
Marlowe has historical context and meaning and the E adds so much elegance.
Eck,
Meadow no. Yuck. Marlow. But honestly, I think the vast majority of people aren't going to know that
Sienna Miller spells it a certain way. If they do associate
Marlowe with her, which they might not (she's not THAT famous), they'll associate Marlow as well. Like people will assume Brangelina
Shiloh, even if it's spelled Shilo.
