John Crosby (died 1476)
Sir John Crosby (died 1476) was a London merchant and alderman, diplomat and Member of Parliament. A Yorkist during the Wars of the Roses, he was knighted for his service in resisting an attack on London in 1471 by Lancastrian forces under Thomas Fauconberg. Crosby Hall, the mansion he built at Bishopsgate, was later moved to Chelsea, where it still survives.
Family
John Crosby was the son of John Crosby of London, from whom he inherited the manor of Hanworth, which had previously been held by his grandfather. His mother's name is unknown. In his will he mentions a cousin, Peter Christmas.
Career
As a youth Crosby was apprenticed to John Young, a member of the Worshipful Company of Grocers. He was made free of the Company in 1454, and became a wool merchant. By 1460 he was dealing on a large scale, and in 1462 was described as 'of London, grocer, Merchant of the Staple of Calais'. In 1465 his former master, John Young, accused Crosby of 'counterfeiting his seal and making a false indenture', and the quarrel between the two had to be submitted to arbitration.
