House Flags of U.S. Shipping Companies: J

Jackson Marine Corp.

  by Jarig Bakker, based on the website of the National Maritime Museum.

From the website of the National Maritime Museum, "the house flag of Jackson Marine Corp., Aransas Pass, Texas. A blue, white and blue triband with the letters 'JMC' in blue across the broader white central stripe (this is double sided). The flag is made of nylon fabric with a cotton hoist. The hoist has a brass eyelet at each end."
Aransas Pass is named for the pass between the islands that link Corpus Christi and Aransas bays. In 1720 the French navigator Jean Béranger, seeking to reinstate the French claim to La Salle's old site at Matagorda Bay, entered Aransas Pass and explored Aransas Bay. He wrote a lucid account and a member of his company made an accurate map.

J. H. Brown & Co.

J. H. Brown & Co., Providence
The same family that endowed Brown University in Providence. The flag is the same as that of Texas, but John H. Brown was already sending ships to China as early as 1787, so there is presumably no connection.
