Chester White

The Chester White was first developed around 1815–1818, using strains of large, white pigs common to the Northeast U.S. and a white boar imported from John Russell Duke of Bedford, Bedfordshire county, England, referred to as the Woburn breed, brought by Captain Jefferies of Liverpool, England.{{cite book | url=https://books.google.com/books?id=14EIAQAAIAAJ&q=Chester+White+Swine+Record+Association&pg=PA7 | title=The Chester White Swine Record | publisher=Van Trump Co. | date=November 1922 | accessdate=October 14, 2014 | author=Moore, F.
