William Mynors was an English sea-captain, master of the East India Company (EIC) vessel Royal Mary. His voyage in 1643 discovered Christmas Island (10°30′S 105°40′E / 10.500°S 105.667°E) on Christmas Day of that year, when he sailed past it and named it.[1] Besides this, little is known of Mynors.[2]
Royal Mary served the EIC from 1626 to 1639,[3] and apparently longer.
