Sorry Anonymous, I have obviously NOT been checking WikiTree in quite some time. I do believe that you were able to get in touch with me as I recall addressing this question.
There were several Geisler families living in Zell am Ziller. This line does not seem to correlate with the one listed in my tree.
My surname is by marriage, and so there is absolutely NO connection regarding my given name. Joseph Geisler who came to the US was the only son who survived according to Salzburg Catholic Archive records. There was a sister, Teresa, who never emigrated to our knowledge.
Good luck, and I do apology for the delay in answering this.
