Charles Law came to the United States on the ship George Washington, a clipper ship built in Boston in 1851. As part of the Williams & Guion Line, Train's Line, and Warren & Thayer's line, this ship made many trips between Liverpool and Boston. In 1857 the ship carried 817 Mormons immigrants from Liverpool to Boston in just 23 days.
The ship set sail on on March 28 from Liverpool when Josiah Cummings was captain. The Mormon immigrants were under the leadership of James P. Park and his counselors Jesse B. Martin and Charles R. Dana. Amos Musser served as secretary for the ship, recording events of the journey. The ship arrived in Boston Harbor on April 20, 1857, but it wasn't until April 23rd that the passengers were allowed to disembark.
The passenger list of those arriving in Boston show Charles Law, age 25, a merchant, as the 9th person listed on this page from the record.
