Ernestine L. Rose--maiden name Siismund Potoski--was born January 13, 1810, at Pyeterkow, in Poland. Her father, a very pious and learned rabbi, was so conscientious that he would take no pay for discharging the functions of his office, saying he would not convert his duty into a means of gain. As a child she was of a reflective habit, and though very active and cheerful, she scarcely ever engaged with her young companions in their sports, but took great delight in the company of her father, for whom she entertained a remarkable affection. At a very early age she commenced reading the Hebrew Scriptures, but soon became involved in serious difficulties respecting the formation of the world, the origin of evil, and other obscure points suggested by the sacred history and cosmogony of her people. The reproofs which met her at every step of her biblical investigations, and being constantly told that "little girls must not ask questions," made her at that early day an advocate of religious freedom and woman's rights; as she could not see, on the one hand, why subjects of vital interest should be held too sacred for investigation, nor, on the other, why a "little girl" should not have the same right to ask questions as a little boy. Despite her early investigation of the Bible, she was noted for her strict observance of all the rites and ceremonies of the Jewish faith, though some of them, on account of her tender age, were not demanded of her. She was, however, often painfully disturbed by her "carnal reason" questioning the utility of these multifarious observances. As an illustration, she one day asked her father, with much anxiety, why he fasted[13] so much more than others, a habit which was seriously impairing his health and spirits; and being told that it was to please God, who required this sacrifice at his hands, she, in a serious and most emphatic tone, replied, "If God is pleased in making you sick and unhappy, I hate God." This idea of the cruelty of God toward her father had a remarkable influence upon her; and at the age of fourteen she renounced her belief in the Bible and the religion of her father, which brought down upon her great trouble and persecution alike from her own Jewish friends and from Christians.
