Hi,

Thank you for your message.

What data exactly do you have on your Adolphs? Do you have the ship's list, date of arrival, firts place of residence?

Do you mean the US or Alsace when you say there are not many around anymore? In the US, there are definitely a lot, some of which I am in contact with.

As to Alsace, there are quite a few families around, but during the French Revolution (1789-92), the name became Adolf then Adolff (my current spelling).

Rossteig (could be Rosteig) is in the north of Alsace, on the provincial border with Lorraine. There are several places called Tieffenbach. Both are small though, which could explain why you can't find them on the atlas.
Have you tried the Microsoft Encarta Atlas? It has some tiny places on it. If you cannot find, let me know I will try to scan a map and send.
