D. Michael Quinn and other Mormon historians have documented that some church apostles covertly sanctioned plural marriages after the Manifesto. This practice was especially prevalent in Mexico and Canada because of an erroneous belief that such marriages were legal in those jurisdictions. However, a significant minority were performed in Utah and other western American states and territories. The estimates of the number of post-Manifesto plural marriages performed range from scores to thousands, with the actual figure probably close to 250. Today, the LDS Church officially acknowledges that although the Manifesto "officially ceased" the practice of plural marriage in the church, "the ending of the practice after the Manifesto was ... gradual."
