Joseph, I just posted a short biography with commentary about St. Martha under the "Blog" section of this website.  I looked but couldn't find a good prayer nor novena for St. Martha - but thought this meditation on her life would be beneficial.  Thank you for suggesting it.  I gained a new admiration for this good saint

A blessed Happy Birthday to you , Joseph. May the Lord bless you on your special day and our Immaculate Mother Mary hold you tightly with in Her loving arms and cover you with Her mantle of protection, always.
