Robert Cushman (1577–1625) was an important leader and organiser of the Mayflower voyage in 1620, serving as Chief Agent in London for the Leiden Separatist contingent from 1617 to 1620 and later for Plymouth Colony until his death in 1625 in England. His historically famous booklet titled 'Cry of a Stone' was written about 1619 and finally published in 1642, many years after his death in 1625. The work is an important pre-sailing Pilgrim account of the Leiden group's religious lives.
