The #Russian princess Anna of Kashin (d.1368) is an unusual saint for taking time off from sainthood. Her biography is unremarkable for a princess of Tver, but her recognition as a saint in the 1600s was jeopardized by the Old Believer schism, because Old Believers favored her. She was canonized in 1649 following a miraculous deliverance of Kashin from siege in 1611, but she was decanonized in 1678, and then recanonized in only in 1908! https://en.wikipedia.org/wiki/Anna_of_Kashin
