Of the sea or dedicated to Mars
Marshae is a modern American invention, likely created by blending the prefix 'Mar-' with the suffix '-shae'. It draws etymological influence from Marcia, meaning 'dedicated to Mars', or Mary, meaning 'of the sea'. Its usage is rare and reflects a mid-to-late 20th-century trend of rhythmic, phonetic name creation.
