Peter Sneddon Allen
Evidence from genealogical records proves the Allen family traveled to Utah sometime between 1865 to 1868. Further research is needed to determine the year they came to Utah and the name of the company they traveled with.
Birth date is confirmed by his death certificate. His surname is "Adamson" on the 1870 Utah census. His mother had married Thomas Adamson in 1869. On the 1880 Utah census his surname is back to Allen.
