1639–1640, c.1621–1670) was a Trinity College alumnus and early member of the Japanese in the United Kingdom.
Eaton was an early member of the Japanese in the United Kingdom, born in Hirado, Japan after his father William Eaton and mother Kamezo (William's common-law wife) met during the period of the opening of the English trade factory East India Company in Japan (1613-1623).
On occasion he appears in the English records as both William or Uriemon Eaton.
[2] Cocks relays how Eaton was taken by his father to live with him in England at a young age after the closing of the English factory in 1623, travelling separately via Batavia on a Dutch ship in 1624, sent by Cocks.
[4] When Cocks died in 1624, Uriemon was accepted and 'maintained' (supported) through his studies by family and friends in England.
