Eliza Ostrander first crossed the plains in 1847 and was re-baptized at Salt Lake City on 12 February 1848. She appears in the 1850 federal census of Utah twice, once in Great Salt Lake County under the name Ostrander and the second time in Iron county with her new husband named Robert Green. She again crossed the plains with Robert and their children in 1857 when they were returning from a mission in the Eastern States. Further research is needed to identify the company they traveled with on this second trip. They are documented on the plains in 1857 by the death of a daughter.
