I would say that the odds are good. The problem we are sll having is that it's "odds" and not facts. We have limited connections with the old country. I intend to head there in the next couple of years and would be interested to see where our stories align.
In my mind this ties in with a migration from the Swiss Jaccards (French Jacquard) through Austria/Bohemia and up to Germany, but there is nothing but similarity between names and occasional geographical references to validate this.
There are people today with the name Tschakert, googling for the name I found a college professor who in a YouTube clip pronounced her name the same way we pronounce our "personal" derivation of it - Jaccard. She has not responded to my email. (don't blame her).
