Since the late 17th century up to the early 19th century, Pacific Ocean charts registered an island named Dona Maria de Lajara, or de Laxara, or even Maria Laxar around 27 degrees North latitude and 140 West from Greenwich longitude (that is East-northeast from Hawaii). As Gemelli wrote, such an island was supposedly near the place were María de Lajara hurled herself into the sea.
However no island actually exists in that area and therefore it is presently catalogued as a phantom island. Anyway, given that in early times latitudes were rather accurate, other possibility is that Dona Maria de Lajara island could originally be one of the Bonin Islands, around 27 degrees North and 140 East from Greenwich; where a small volcanic island is at this location; and the longitude shortly later mistakenly moved to 140 West.
The mercator map however places the island just north of Hawaii (Sandwich Island)
