Eliza Jane Godfrey
There is also an Eliza Jane Godfrey born on December 14, 1846 in Winter Quarters on the Ancestry.com site but i think they are interchangeable daughters that both or in reality just one died before the trek West.
Most likely died before 1852 becasue he didn't come across the plains with his family in 1852.
The Mormon Pioneer Overland Travel records say she died on the trek but the Census says that she made it to Utah and was 1 year old. I don't know which record is right.
