The 1860 US Census for Nevada City, California shows the following family group: William Kent, age 39, born in VT, druggist; Wm. H. Kent, age 17, born in VT; J. Kent, age 15, born in VT (female); E. B. Kent, age 13, born in VT; C. B. Kent, age 1, born in CA; J. W. Barnum, age 65, born in VT; L. C. Barnum, age 49, born in VT. For some reason the mother of this family, Julia H. Barnum, is not enumerated with the family. Although the dates are a few years off, it appears that the two male Barnums in this family group were Jasper W. and Loyal C. Barnum, uncles of Julia H. Barnum. In a separate household in the same place (enumerated with the Meek family) was J. H. Kent, age 45, born in VT, (male). He might possibly have been a brother of William Kent.
