Who is St. Gerard?

St. Gerard is the patron saint of expectant mothers.  In my "googling" for IVF, his name popped up.  I looked into it more to find out about him.  I will say I've said some prayers to St. Gerard.  The talks I've had with St. Gerard have increased as we get closer to IVF.  I fully believe that God has a plan for us.  When He is ready, He will give us a child.  We just have to wait and be patient.
