Hi Mike! I am Patricia Hetzel's daughter and was searching Peter Hetzel and the Jaekel family for my 8th grader's ancestry assignment and found your posting :) if you are interested, I have a book documenting the Hetzel side that I'd be happy to make a copy of and send you! I think the "Emma" listed in my baby book must be Emma Immel! My daughter 'Emily' is named for her! I hope this message reaches you and will keep my fingers crossed :) Kristin p.s. my great aunt Rosemary is still alive and living in Arizona!!!
