John M. Freeman was part of the 1st Company of Ten led by Wilford Woodruff. His birth date and death date come from family search inquiries, original research of public documents, and information taken from his tombstone and profile on findagrave.com. There is some conflicting information pertaining to his middle name. Some sources suggest that his middle name was "Monroe" while other sources indicate his middle name was "Merrick." This should be taken into consideration when completing historical research.
Date of death requires further verification. "The Utah Pioneers," in the Deseret Weekly, indicated that he died in Carson Valley, Nevada in 1850. This information is supported by a statement in volume 4, page 86, of The Utah Genealogical and Historical Magazine that states he died of cholera in Carson Valley, Nevada in 1850. The date listed on FamilySearch and on Find a Grave may be incorrect.
