I think that Rinteln is a part of Niedersachsen. I am sorry to be so ill informed about it. I have Christoph Rintelmann who arrived in Philadelphia, Pa on 12 Dec 1754, from Germany on Ship Neptune. Family tradition says he was from Rinteln, which is like his name. Family tradition also says his family had been there for 300 years. On an early map of Germany, around 1700, I saw in a circle the words "Ducy of Rinteln." don't know what that means, but in trying to find where this Christopher was born and married, etc. I am seeking ideas of what to do. I know there is a town called Rinteln and because of the map I saw maybe there was an area in Christoph's time. Thank you for any ideas. Marla Goodrich
