This information comes from the Mormon Immigration Index- Voyages section of Databases at the Family History Library:
Ship: William Tapscott
Date of Departure: 11 April 1859 Port of Departure: Liverpool, England
LDS Immigrants: 725 Church Leader: Robert F Neslen
Among the notes we find this:
On Monday Apr 11 1859 the ship William Tapscott sailed from Liverpool with 725 British, Scandinavian and Swiss Saints on board. . . Elder Robert F Neslen was appointed president of the company with Henry H Harris and George Rowley as counselors. . . the company was blessed with a most pleasant and agreeable voyage. . . Elder Neslen writes that he felt it quite a task when he was appointed to take charge of a company composed of people from so many countries, speaking nine different languages anad having different manners, customs and peculiarities and thrown together under such close circumstances.
Among the passengers we locate the names George Kirkham, Mary Ann Kirkham, James Kirkham, George Kirkham, Hyrum Kirkham and Joseph Kirkham with their approximate year of birth (based on age given in passenger ledger). There is a painting among the artworks in the LDS holdings that represents the shipping docks of Liverpool, England. It is not of a Carnival Cruise advertisement for sure. I will do my best to have a copy of that painting available to help you imagine Monday April 11, 1859 when we meet to recognize and honor these six ancestors.
