Esquemeling's Book

Pretty much everything we think we know about pirates of yore comes from one of two places - the fictional Treasure Island by Robert Louis Stevenson and The Buccaneers of America by Esquemeling. Treasure Island had a lot of apocryphal tidbits that have been picked up by popular culture (e.g. parrots, peg legs, and eye patches, and the "Arrrgh" that we all love so well). On the other hand, this Esquemeling dude was a pirate contemporary that lived and sailed among them.

This edition is from 1893, and it lists the author as "John Esquemeling", even though his name was "Alexandre Olivier Esquemeling". The text is identical in all other respects to A.O. Esquemeling writings on the Internet Archive, so I'm wondering is this isn't a typographical error of an Anglicanization in order to make the book more acceptable to English speaking readers...
