Elias Copeland
Jefferson Copeland is documented in this company as traveling with his wife and two children. Just the line below there is "Elias Copeland" also listed as if he is another head of household. The two children still in Jefferson's household at this time would have been his daughter Juletta and son, Elias. It is likely the Elias listed is actually Jefferson's 2 year old son, rather than another adult by the same name.
The entire family returned to Iowa after only a short stay in the Valley.
