The following returning missionaries form England, were also on board -- Matthias Cowley, Henry Lunt, Lorenzo D. Rudd, and George W. Thurston, making 544 souls in all.
These brethren have done a good work as missionaries in England, and return to their families, and the bosom of the Church, with the blessings of God, and of their brethren, upon their heads.
Elder Matthias Cowley was appointed president of the company, with Elders Henry Lunt and Olaf N. Liljenquist as his counselors.

"ONE HUNDREDTH COMPANY. -- Westmoreland, 544 souls. The ship Westmorland, Captain Robert R. Decan, sailed from Liverpool April 25th, 1857, with five hundred and forty-four Saints on board, of whom five hundred and forty were from the Scandinavian Mission the other four were Mathias Cowley, Lorenzo D. Judd, Henry Lunt, and George W. Thurston, returning missionaries from Great Britain. Mathias Cowley was appointed president of the company with Henry Lunt and O. N. Liljenquist as his counselors. The emigrants had sailed from Copenhagen, Denmark, on the steamer L. Hvidt, on the eighteenth of April, in charge of Hector C. Haight, then presiding over the Scandinavian Mission, who accompanied the Saints to England. Arriving at Grimsby on the twenty-first, they continued the journey by rail the following day to Liverpool. The voyage across the Atlantic Ocean lasted thirty-six days, during which time the usual good feelings, harmony and union characteristic of Latter-day Saint emigrants prevailed. An old man and two small children died on ship board and five couples were married; one child, named Decan Westmoreland for the captain and the ship, was born. On the thirty
-first of May the company arrived at Philadelphia, when the emigrants were received by Elder Angus M. Cannon who, in the absence of John Taylor acted as emigration agent at that port. The necessary arrangements for the continuation of the journey were quickly made, and on the second of June the company left Philadelphia for the West. Traveling by rail via Baltimore and Wheeling they arrived in Iowa City on the ninth of June. Three children and a brother from Bornholm, Denmark, died while journeying by rail. Most of the emigrants crossed the plains immediately afterwards in Captain Mathias Cowley's wagon train, and Christian Christiansen's handcart company, while the remainder, who lacked means to continue the journey to the Valley, stopped in the States, in order to earn money for that purpose. (Millennial Star, Vol. XIX, p.313, 411, 445; Morgenstjernen, Vol. III. p.52.)"
