Hello Linda,
There is a society called "Naturwissenschaftlicher und Historischer Verein f�r das Land Lippe e.V." or NHV Lippe e.V. (Scientific and Historical Society for the Country of Lippe).
They run a specific website on emigration from that area to the US.
It might be worth to take a look at the website and contact them. Christoph Breitenp�hler appears in their database of emigrants.
And as Sonja already mentioned, the easiest way to search for further ancestors is to go to a Family History Centre of the LDS.
Best regards,
Simone
