Eliza Manwaring was an English convert to the Mormon Religion and immigrated to America. Shortly after getting married she joined her husband on the march of The Mormon Battalion from Iowa to the West. Somewhere in Kansas they left the Battalion with one of the Sick Detachments (probably the first group). On Sept 8th, somewhere in Kansas, she gave birth to her first child, Fent Allred (1846-1846) who died the same day.
They wintered in Pueblo CO and then continued on to settle Salt Lake County, Utah where her second child was born in 1848. By 1850 they were farming in Sanpete County, Utah where they appear on the US Census living adjacent to some prominent Mormon Pioneer families there. Her husband took additional polygamous wives.
Offspring of James TS Allred and Elizabeth Bridget Manwaring (1821-1866)
James and his young family living in San Pete County, Utah. Notice that son Nephi (born in 1849) is missing from this census and presumed dead. There area also two older siblings from Illinois living with the family. James and Eliza's children are the two born in "Deseret" the early name of Utah Territory.
