As I am reading these mysteries, I notice a lot of the information is outside of scripture. It is making me wonder where this information came from. Perhaps an apparition of Mary revealed this to someone a long time ago.

lot of the information???

Just which of the mysteries do you think is outside of scripture? And it would only matter if they were also outside of the teachings of the Church.

Rev. Fr. Fanfani, O. P., in his work De Rosario B. M. Virginis: Historia - Legislatio - Exercitia (Turin, Rome: Marietti, 1930), defines the Rosary Mysteries as follows (loosely translated) (cap. 1., §. II):

That which are named Mysteries of the Rosary are certain fragments of evangelical narration which refer to the principal acts of the life of Jesus and Mary. They are historical facts which occurred in Palestine, where twenty centuries ago our Redemption was wrought and consummated. But they are called "Mysteries," that is, things secret and arcane: those truths which are under the veil of history as they are impervious to our reason; such as, for example, the Incarnation of God the Son and the Virginal Maternity of Mary Most Holy. These Mysteries exceed altogether the grasp of created intellect, and have been made known to us solely by divine revelation.

Later (cap. 1., §. V), Fr. Fanfani cites the venerable tradition that it was Our Lady who revealed the form of the Holy Rosary as we know it to St. Dominic but the earliest docuмented evidence was published by Blessed Alanus a Rupe (also known as Alan de la Roche) in his oft-cited treatise upon the origin of the Holy Rosary in the 14th century.

The devotion of a lay Psalter that consisted of Our Lord's Prayer and the Angelical Salutation was around since ancient times, and the faithful meditated upon the principle Mysteries of our Redemption, the Mysteries which were codified and given to St. Dominic, as is piously believed.

Fr. Fanfani does not dare to question such a venerable and ancient tradition, especially since the Roman Pontiffs have often spoken of it as if it were established and the lessons at Matins for the Feast of the Holy Rosary in the Roman Breviary still record it. He cites the testimony of Pope Benedict XIV who answered historical doubts as follows (loosely translated):

Ye ask whether S. Dominic was verily the institutor of the Rosary, and ye shew yourselves implicated in perplexing doubts? Yet how much do you make of the testimony of so many Supreme Pontiffs, Leo X, Pius V, Gregory XIII, Sixtus V, Clement VIII, Alexander VII, Innocent XI, Clement XI, Innocent XIII and others who unanimously ascribed the institution of the Rosary to St. Dominic, Founder of the Order of Preacher [...]

The Rosary Mysteries are indeed found in Holy Writ. The Joyful Mysteries are found in the first two chapters of St. Luke (and St. Matthew also records the Incarnation, the Virginal Maternity of Our Lady and the Nativity of Our Lord). The Sorrowful Mysteries are found in the four Gospels when narrating the Sacred Passion of Our Lord. The First Glorious Mystery is recorded by all four Evangelists; whilst St. Mark and St. Luke (both in his Gospel and in the Acts of the Apostles) record the Second Glorious Mystery, with the Third Glorious Mystery being recorded by St. Luke in the Acts of the Apostles. The Fourth and Fifth Glorious Mysteries are found implicitly in Holy Scripture in their Old Testament types (Judith, Esther, the Canticle of Canticles, the Psalms, &c.) and in the solemn definition of the Dogmas of the Immaculate Conception and the corporeal Assumption of the Blessed Virgin (so the Fourth Glorious Mystery has been clearly defined as dogma, divinely revealed and taught by the Church always and everywhere) - the Fifth Glorious Mystery is a consequence of the prerogatives of Our Lady in the two aforementioned dogmas and Pius XII taught the doctrine of the Queenship of Our Lady (summarizing the teachings of the Fathers, Doctors, Saints and theologians) explicitly and established a Feast Day of the Blessed Virgin Mary Queen for 31 May in his Encyclical Letter Ad caeli Reginam (11 October 1954).

The Holy Rosary is uniquely Catholic as it shows the deposit of the faith as consisting in a wondrous unicity of Sacred Scripture and Apostolic tradition, under the guidance of the magisterial authority of the Apostolic See, that contains those truths which a Catholic ought to believe and the examples of Our Lord, Our Lady and the Saints, which he must practice if he is to remain faithful to his profession as Christian and to the sacred Baptismal vows.

I think you brought something to my attention when you mentioned the part about the Old Testament. That makes sense now. I just read an article about how in the Old Testament it states...

"Say to the king and the queen mother: "Take a lowly seat, for your beautiful crown has come down from your head." (Jeremiah 13:18).

"So Bathsheba went to King Solomon, to speak to him on behalf of Adonijah. And the king rose to meet her, and bowed down to her; then he sat on his throne, and had a seat brought for the king's mother; and she sat on his right." (1Kings 2:19)

These versus would foreshadow Jesus and Mary as King and Queen in the New Testament. This is narrated in the 5th glorious mystery, and I was trying to figure out where in Scripture it says this. Now I know that the Old Testament plays a role in the mysteries of the Rosary.

So basically, everything in the mysteries is mentioned in both New and Old Testaments. I think my question has been answered. I was thinking that some of the information in the mysteries was completely outside of scripture.
