Lives of the Saints

Question from Laurel DeStefano on 1/22/2008:  
I've noticed over the years as I read the lives of various saints, especially of married women saints, that some of them seemed to neglect their motherly duties in order to found religious houses or do the work of God. St. Jane de Chantal, St. Paula, and St. Elizabeth Seton come to mind. Most faithful Catholic mothers I know would never consider such a thing as leaving her child voluntarily, as they would consider that their first duty. Is there something cultural that I just don't understand? Also, can you recommend any saint biographies about married saints? Thank you.
Answer by Fr. Jay Toborowsky on 2/26/2008: 
I don't know of any biographies that you ask about.
