Albert P. De Valengin's Administrators, Plaintiffs in Error v. John H. Duffy

This case comes here, upon a writ of error to the Circuit Court for the District of Maryland. It appears from the record, that John H. Duffy, an American citizen, being engaged in commerce and domiciled at Buenos Ayres, shipped a cargo of hides and lard to Gibraltar, on board the brig President Adams, in 1828. Buenos Ayres was then at war with Brazil. The President Adams was an American vessel; and De Valengin, her captain, was a citizen of the United States. He was also part owner of the vessel.
