Hi Elizabeth, I am probably not directly related to you but the Kranz name is so unusual that I guess we all feel kind of related anyway. My grandfather was Albert Kranz who came to NYC from Lyon France in the 1870's. Try to get as many dates and family members to give you whatever info they have. There is also a listing of passengers that came to America under the Immigrant Ships Transcribers Guild. It is not a complete list but you never know. Also, I've found in searching the Kranz name that sometimes it is spelled Krantz. My grandfather,Albert Kranz had a brother George but he stayed in France from what I know. Anyway, happy hunting. Genealogy can get frustrating but hang in there cause it's lots of fun, too.
