The Archibald family arrived in New York on 6 July 1866 via the ship Arkwright. Although only Robert is listed as head of household on the overland company records, the notation that he purchased two adult food rations indicates that his wife was with him during that part of the journey as well. As an infant, Elizabeth would have been with them as well.
Birth and death date is confirmed by her grave stone.
The Wellsville Ward financial records confirm that she was traveling in the same company with her husband.
