Charles Williams
Charles and his family crossed the Atlantic on the ship Sailor Prince in 1848. His wife (Mary Griffiths Williams) died at St. Louis in 1850. Charles was re-baptized in Utah on 19 October 1850. In the 1850 Utah census (taken in early 1851) Charles is in a household with his daughter (Sarah) and his son (John). Charles' death date is from his tombstone.
Charles' son John does not appear on the Roundy Company roster, but given his age it seems certain that he would have been with the rest of his family.
