Hi Pat!
My Father-in-Law happens to be Lee Ambrose Kann who's Great Grand Parents is William and Mary Jane. He was just sharing stories with me the other night about how it was growing up in Guttenburg and the family history. Lee was actually in the community Guttenburg Press many times throughout the years. I did find a Pelzer family tree on his grandmother's side includes his grandparents (William Hubert Kann and Josephine Angelina Pelzer) at http://www.alpinecom.net/austin/Pelzer.htm.

I'd also suggest contacting those mentioned by Dave Kann. Kann Imports is still owned by Barbara Kann (sister of Lee) and daughter of Carl and Juanita. I'm quite certain Barbara will have all the information you'd like. Awesome family!
