With all the hacking, editing, suppressing, altering and retooling that the Mormon church has done to the records of their own history it's impossible to know what really happened whenever they were involved.
I am absolutely floored that anyone can call themselves a Historian and work for, or under the thumb of the Mormon Church with their blatent disregard for the truth.
I guess it wasn't enough to edit the Holy Bible with the Joseph Smith Translations, they actually had to continue engineering the truth for the next one hundred and eighty years......
