Got this from a former Wikitree'r,
Hi Nick:
The catalog entry at familysearch.org indicates that the article you are looking for is a translation of a German article. A PDF of the German article can be found at
https://www.zufallsfunde.net/Medien/Auswanderer-Zweibruecken-1750-1771.pdf. Because this has been OCR'd, you can use Google Translate to render it into English if you cannot read German.
In essence, this list is based on a file of the "manumissions" (that is, governmental permissions to emigrate because all local obligations have been satisfied) for the principality of Zweibrücken for the years 1750-1771. The file indicates that Görg Hechler of Ingolsheim (now in France, just east of Birlenbach, see
https://en.wikipedia.org/wiki/Ingolsheim) received permission in 1754 to emigrate with his 5 (unnamed) children. The author of the article then linked this entry with the arrival in Philadelphia of Georg Hechler 30 September 1754 on the ship Neptune.
This information kind of clouds things--all other sources point to Georg arriving on 14 Sep 1754 on the Barclay. I also note that some of the other entries list "mit Frau und 6 Kindern" or "mit Weib" and Georg is just with his children.....
I appreciate the response X!
