沉夭
[chén yāo]
Chen Yao could imply two meanings depending on the characters used: one could mean premature end or downfall ('沉', chén meaning heavy or deep, and '夭', yāo meaning young or to die young); another could mean someone who is submerged in serenity ('沉静的夭'). This might reflect a character that is both deep and tranquil.
