Although we associate a Queen with a King, it can be defined more broadly meaning "a woman foremost or judged to be foremost among others in certain attributes or accomplishments." (Webster Dictionary)

In the stained glass we see Ann, mother of Mary, holding the child who was the most beloved creature of God from the first moment of conception, "far above all the angels and all the saints so wondrously did God endow her with the abundance of all heavenly gifts poured from the treasury of his divinity that this mother, ever absolutely free of all stain of sin, all fair and perfect, would possess that fullness of holy innocence and sanctity than which, under God, one cannot even imagine anything greater, and which, outside of God, no mind can succeed in comprehending fully." (Pius IX: Ineffabilis Deus) Mary was, therefore, from the beginning a Queen in the order of nature and grace. This God did because she was destined to become the mother of his only-begotten Son.
