Sarah
Sarah was the wife of Abraham. She was very beautiful even in her old age.
Her Hebrew name means Princess, the mother of the nations.
She was born in about 2155BC, had a son at 90 in 2065BC, and died at age 127.
She was one of the notable women of the Bible. Her former name was Sarai, which in Hebrew means Jah is prince in Hebrew.
She was also a half sister to Abraham as they had the same father, Terah, but not the same mother.

Sarah
29 Abram and Nahor both married. The name of Abram's wife was Sarai, and the name of Nahor's wife was Milcah; she was the daughter of Haran, the father of both Milcah and Iscah. 30 Now Sarai was barren; she had no children.
31 Terah took his son Abram, his grandson Lot son of Haran, and his daughter-in-law Sarai, the wife of his son Abram, and together they set out from Ur of the Chaldeans to go to Canaan.

More Information:
Most people know Sarah as the barren wife of Abraham. She was also his half-sister (same father--different mothers), which came from tribal marriage alliances in Hebrew times. This is how (in Genesis) Abraham could claim to the Egyptians that Sarah was his sister.
