The Haight family traveled to the Salt Lake Valley with the Daniel Spencer/Ira Eldredge Company in 1847. The Haight family included Hector Caleb and his wife Julia Ann, and their children Mary, Horton, and William. Hector Caleb was a Captain of Ten.
Also traveling in the Daniel Spencer/Ira Eldredge Company was William's Grandfather, Caleb and his wife Sarah Aldridge Martin.
William's uncle Isaac Chauncey, his wife Eliza Ann Snyder, and their children Caroline Eliza and Temperance Keturah also traveled in the company.
William 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.
