Martha Holdsworth
Her birth and death dates are confirmed by her obituary. It also confirms the travel of her family to Utah in 1866.
A secondary source on her "memories" section of FamilySearch states that she, Eliza, Heber, Jedediah, and Martha Harriet sailed to America in 1865 on the ship City of Virginia. We have not been able to locate any information regarding that ship.
