SERYOSS, Thomas Lowery, merchant, born in Philadelphia, Pennsylvania, 14 October, 1786; died in New York city, 30 November, 1866. He was educated in his native city, and then engaged in the shipping business. In 1808 he settled in Natchez, Mississippi, where he purchased cotton and sold goods that were consigned to him from the north, and in 1817 he moved to New Orleans, where he continued his mercantile career. Meanwhile, in 1814, when the seaports of the United States were threatened by the British navy, Mr. Servoss was in New York, and, on learning that New Orleans was about to be attacked, he left at once for that city by way of Pittsburg, where he found two keel-boats laden with muskets. He took passage on one of these, and by his knowledge of river navigation he placed his boa, t in advance of others, in consequence of which the United States troops received the arms; otherwise, as has been said by John H. Eaton in his "Life of Andrew Jackson," New Orleans would have fallen into the hands of the British. In 1827 Mr. Servoss settled permanently in New York. He built, in 1831, the first five packet ships that ran regularly between New York and New Orleans, and was agent of the line. Mr. Servoss was active in charitable enterprises, and held office in various benevolent societies. He contributed articles on popular topics to journals, and presented a series of historical reminiscences to the New York historical society in 1858. He married daughter of John Pintard.
