Circumstantial evidence from census and genealogical records proves the Campkin family traveled to Utah in 1850. The death of one child (Mary) in St. Louis after the departure of all Utah-bound emigrant companies in 1849 and the birth of another child (Elizabeth) in Utah in late 1850 proves that the Campkin family could only have traveled to Utah in 1850.
The family sailed to America in 1844 on the ship Norfolk. The ship manifest lists their surname as "Compkin."
Their surname is shown as "Camkin" on the 1850 Utah census.
