As part of this accord, the Church took the extraordinary step of removing 260,000 names of Jewish Holocaust victims from its publicly available International Genealogical Index. In addition, the Church said it would cease all temple baptisms of known Jewish Holocaust victims except for those who are ancestors of living members of The Church of Jesus Christ of Latter-day Saints. And, because names are submitted for temple baptism by hundreds of thousands of members across the world, the Church established procedures to remove names we find to have been submitted contrary to this policy.
