The website MormonLeaks says Chief Seattle was baptized posthumously in the Mormon church.

The website released purported baptism documents for 17 long-dead people. One set of documents says the famous Native American for whom the City of Seattle was named was baptized in 1991.

A representative for the Church of Jesus Christ of Latter-day Saints in Salt Lake City said Tuesday that the church doesn’t comment on the authenticity of leaked documents.

Ryan McKnight, founder of MormonLeaks, said in an email: "We stand by all of the documents we have released so far including the ones today."

The documents show that Chief Seattle, an ancestral elder of the Suquamish Tribe, was referred for baptism three times in 1991. A spokeswoman for the Suquamish Tribe said they hadn't heard of this baptism but didn't want to comment further without knowing more details.
