On Saturday, a member of the Church of Jesus Christ of Latter Day Saints, was said to have performed the ceremony posthumously, according to whistle blower Helen Radkey.
Radkey, a Salt Lake city researcher and former member of the church, discovered that Anne Frank, who died in a concentration camp at 15, was baptized by proxy over the weekend.
The situation also stirred conflict between the two religions, as the Mormon church vowed to stop the posthumous baptisms. But the ritual has been carried out at least nine times in Frank's case, over 10 years, from 1989 to 1999. Radkey said she made the discovery of the incident when Frank's name appeared in a database for proxy baptism, which is usually only open to Mormons.
The discovery is reportedly the first time in more than a decade in which Frank's name has appeared. Talks amongst Mormon and Jewish leaders led to an agreement in 1995, which called for the Mormon church to stop the baptisms of Jews, unless the person is a Mormon ancestor.
Frank, however, was only a teenager when she died and left no descendants, which Radkey said she found to be even more egregious of the mistake. Officials of the Mormon church have stressed, however, that all church members are supposed to submit the name of their ancestors, to comply with the agreements.
Spokesman Michael Purdy, issued a statement on Tuesday to the Huffington Post: "The Church keeps its word and is absolutely firm in its commitment to not accept the names of Holocaust victims for proxy baptism."
