According to the ship passenger lists at the National Archives, William and Isabella Cook arrived at Philadelphia on 18 Jun 1832 aboard the ship ASIA which had sailed from Londonderry, Ireland. The information contained on the passenger list was recorded in this manner.

The family at that time consisted of William, Isabella, Margaret, Elizabeth A. and John R. John's age was probably not included because he was an infant.

William filed his Declaration of Intention to become a citizen on 15 June 1846.
