Born in Latvia, Herzog grew up in London.
She was the daughter of Rabbi Shmuel Isaac Hillman, who invited Belfast Rabbi Isaac Herzog (Yitzchak HaLevi Herzog) to his home for a conference regarding kosher dietary laws during World War I rationing in 1917.
According to family history, Sarah dropped a tea tray when she saw Isaac, who was also immediately smitten (in some versions, Sarah spilled tea all over Isaac).
 
In August 1917, Sarah married Isaac and assumed the title and responsibilities of a rebbetzin, or rabbi's wife.
A year later, their son Chaim was born, in Belfast.

The Herzogs moved to Dublin in 1919, where their son Yaakov was born in December, 1921.

The family moved to Israel in 1936, where Isaac Herzog became the Chief Rabbi of Eretz Israel.

Later in his life, Chaim remembered his mother as clearly the dominant individual at home.
She was very pretty and gracious and, although petite, almost regal in her demeanour.
Wherever her home was, it was a centre of grace and culture and, later, in Israel, a magnet for the Jewish community from around the world.
In his inaugural address as president of Israel in 1983, Chaim spoke at length of the influence of both his parents and of his mother, a personality in her own right.
Her grandson remembered her as welcoming and hospitable, especially towards the impoverished.
