Sarina

Meaning unknown, perhaps a diminutive of SARA or a variant of SERENA.

SARAH   female   English, French, German, Hebrew, Arabic, Biblical, Biblical Hebrew
Means "lady, princess, noblewoman" in Hebrew. In the Old Testament this is the name of Abraham's wife, considered the matriarch of the Jewish people. She was barren until she unexpectedly became the pregnant with Isaac at the age of 90. Her name was originally Sarai, but God changed it at the same time Abraham's name was changed (see Genesis 17:15).

In England, Sarah came into use after the Protestant Reformation. A notable bearer was Sarah Churchill (1660-1744), an influential British duchess and a close friend of Queen Anne.
SERENA   female   English, Italian, Late Roman
From a Late Latin name which was derived from Latin serenus meaning "clear, tranquil, serene". This name was borne by an obscure early saint. Edmund Spenser also used it in his poem 'The Faerie Queene' (1590).
