William initially traveled to the Salt Lake Valley in the Brigham Young Pioneer Company in 1847 and was part of the 7th Company of Ten led by James Case. However, he later participated as one of the rescuers that were sent out in the winter of 1856 to assist the members of the Church stranded in Wyoming.
At the end of a mission to Quebec, he traveled home with his friends Robert Gardner and David Brinton with the John W. Berry Company in 1858 as indicated in a biography compiled by Alaine Gardner Bracken on familysearch.org.
His surname is "Carlin" in the Goddard journal. In some sources his birth month is listed as September, but that is incorrect.
His birth date and death date are confirmed by the inscriptions on his gravestone.
