Carolyn/Emile,
I am also researching the Pass family tree. My wife is a great-great granddaughter of Peter H. Pass.
Elizabeth is the only Meuffels that I currently have listed in my database and that was hard to ascertain from the misspelled death certificate.
I would be happy to share any information that I have. About 90% of my research has been in the Carver and Sibley county area of Minnesota. There are also about a dozen family tree that I am working on. All of which have their American roots in Carver and Sibley county so we may have some other surnames of interest.
Steve
