Sarah or Sara was the wife and half-sister of Abraham in the Old Testament book of Genesis (Chapters 12-23). They got married in Haran. She had a child with Avraham named Isaac when she was 90. She lived until she was 127, and was buried by Abraham in Hebron in what is now the West Bank. Her name was Sarai but God changed it to Sarah.
Sarah (also spelled Sara) is also a popular Hebrew female name in English. It means 'princess'. If you lived in Spain, the name would mean, "Fairy".
