Ephraim Stockwell Snyder
Some sources place him in the 1848 Willard Richards company, but there is reason to doubt the accuracy of those sources because they are not contemporary. The best evidence that he didn't come to Salt Lake in 1848 is that his name doesn't appear on the list of those who were alotted land that year.
