I have finally confirmed the identity and name spelling(s) of my Ishler ancestor. His name was Ludwig Ischler, and he emigrated in 1765 through Rotterdam to Philadephia. His name is also listed as Istler and Ishler, but I have his signature on the ship's log, and Ischler is written. I never asked you how you pronounce your name, I assume it is a "long I", as in similar to Eisler, and not a soft I as in "ish" or dish? The Issler name spelling seems more likely to be a soft I, and pronounciations certainly changed over time, as you said, with accents, etc. I have no new information on German/Swiss origin of my family, other than that there are living Eschlers in Switzerland. What information do you have on religion? Many of the Swiss were anabaptists/mennonites. Any record of that in your family? Of course, New Bern may have had an active group, and conversion is always a possibility. My Ishlers were Reformed or Lutheran.
