The United States Conference of Catholic Bishops (USCCB) has chosen a saint to focus on for each month of the Year of Faith.
October was St. Isaac Jogues, S.J.; November, St. Frances Xavier Cabrini; December, St. John Neumann; and January, St. Elizabeth Ann Seton.
February's saint is St. Rose Philippine Duchesne. St. Rose became a member of the Visitation nuns at age 19; her order was shut down during the French Revolution and she returned to lay life for a time; in 1818, she joined the Society of the Sacred Heart and was sent to the Louisiana Territory in the U.S. to bring Catholicism to native Americans. Her nickname was the 'Woman Who Prays Always.'
Here's more about St. Rose on the Vatican web site.
