At least six Seafords exist in the world: Seaford, on the south coast of England; Seaford, Delaware, and Seaford, Virginia; Seaford, Long Island, New York; Seaford, Victoria, Australia, and Seaford, South Australia, Australia.
When using a search engine, please be aware of the six locations.
William Garnett Payne was a prominent and prosperous citizen of Seaford. I just came across a summary of his life (1870-1940) in the website Find-A-Grave, linked HERE.
