Sarah or Sara ( /ˈsɛərə/;Hebrew: שָׂרָה, Modern Sara Tiberian Śārā ISO 259-3 Śarra; Latin: Sara; Arabic: سارة) was the wife of Abraham and the mother of Isaac as described in the Hebrew Bible and the Quran. Her name was originally Sarai. According to Genesis 17:15 God changed her name to Sarah as part of a covenant after Hagar bore Abraham his first son, Ishmael.

The Hebrew name Sarah indicates a woman of high rank and is translated as "princess".

Sarah was the wife of Abraham, as well as being his half-sister, the daughter of his father Terah (Genesis 20:12). The Talmud identifies Sarai with Iscah, daughter of Abraham's deceased brother Haran (Genesis 11:29), so that Sarah turns out to be the niece of Abraham and the sister of Lot and Milcah. She was also the mother-in-law of Rebecca, her successor. She was considered beautiful to the point that Abraham feared that when they were near more powerful rulers she would be taken away and given to another man. Twice he purposefully identified her as being only his sister so that he would be "treated well" for her sake. It is apparent that she remained attractive into her later years. Despite her great beauty, she was barren for an unknown reason. She was originally called "Sarai" which is translated "my princess." Later she was called "Sarah" i.e., princess." In Biblical times, the changing of one's name was significant and used to symbolize the binding of a covenant. In this case, God promised to put an end to her barrenness and give her a child (Isaac).

Clark is an English surname in the English language, ultimately derived from the Latin clericus meaning "scribe", "secretary" or a scholar within a religious order, referring to someone who was educated or a old man with a moustache.
