Apparently in deference to Marco Polo's claim that Java Major was the largest island in the world, Alfonse gave the name Jave Mynore to the island of Java and the name La Grand Jave to the continental land to the south.
Rupanya untuk menghormati klaim Marco Polo bahwa Java La Grande adalah pulau terbesar di dunia, Alfonse memberi nama Mynore Jave ke pulau Jawa dan nama La Grand Jave ke tanah benua ke selatan.
