Esther Muller was born on November 5, 1820, in a small Prussian town near the Luxembourg border. Her parents are Jacob Muller and Sara Aron.

In December of 1825, a tragedy occurred with the sudden passing of Sara Aron. She had no preexisting illnesses, and the cause of her death remains unknown to this day. Left behind were her husband Jacob and their five-year-old daughter Esther. Jacob was devastated by the loss and transformed from an optimistic, hard-working man into a quiet and reclusive individual. Nonetheless, he did everything in his power to be there for his daughter.

In 1830, tragedy struck once more when Jacob Muller passed away on September 9th due to some health complications. This was only five years after losing his wife. It's believed that his heart was broken. Consequently, Esther, his only daughter, was left as an orphan and was taken in by an anonymous Jewish family residing in Germany.
