This series holds the written registries of enrolled members within the Province. Usually upon payment of an erollment fee and the direction of a Dominican friar, names were written down in a book for their particular parish or region's confraternity.

This series contains seven volumes housed in two boxes. The first box holds four volumes and the second holds three volumes alongside the devotional materials series within this collection.

Materials in this collection reflect the work of the Most Holy Rosary Confraternity in promoting Marian devotion. Records include membership ledgers, correspondence, canonical forms, spiritual materials, and promotional campaigns.
