Someone on here told me that you are not allowed to take the Theotokos as a patron.
In addition to what others have said, there are many women who are named Maria and who celebrate any one of the Theotokos' feastdays - I know of a few who celebrate Sept 8 (her nativity), and a few who celebrate Mar 25 (including one whose name is an ancient Greek name for 'God's Flower' and celebrates Mar 25 - Panagia the "Unfading Rose"), in addition to the majority who celebrate Aug 15.
"O Cross of Christ, all-holy, thrice-blessed, and life-giving, instrument of the mystical rites of Zion, the holy Altar for the service of our Great Archpriest, the blessing - the weapon - the strength of priests, our pride, our consolation, the light in our hearts, our mind, and our steps"
