Saint Anne was acclaimed a saint very early, she was the mother of the Blessed Virgin Mary, and thus the grandmother of Our Blessed Lord. There is nothing recorded about her in the Bible, and very little in tradition, so all we know about her is that she must have been an outstanding mother, as God chose her above every other woman in history to raise His Mother.

We know little about St. Elizabeth except that she was the mother of St. John the Baptist, wife of Zacariy and a cousin of the Blessed Virgin Mary.

Saint Anne is considered a saint mainly due to her role as the mother of the Virgin Mary and the grandmother of Jesus Christ. She is also believed to have exhibited virtues such as faith, patience, and humility throughout her life, which have contributed to her veneration by the Catholic Church and other Christian denominations.
There is no saint named Stephanie but there is Blessed Stephanie (Stephana de Quinzanis) who became a Dominican nun at the age of fifteen. She bore the mark of the stigmata, the wounds of Our Lord.
