Oswald Swan (1835-2 May 1890), also called Oswell S. Swann, was a free wesort (Black, white, and Indian) man who lived near Bryantown, Maryland during the 1860s. On 15 April 1865, the fugitives John Wilkes Booth and David Herold paid Swan to guide them to Confederate sympathizer Samuel Cox's Rich Hill home, and they paid Swan $12 the next day for his assistance. He lived in Washington DC during the 1880s and died in 1890 at the age of 55.
