Below is a copy of a reply I got concerning the Boland's in
Germany. Maybe it will lead you to some more info.

I think that unfortunately, most people only associate the Boland name with Ireland. The name I found originated in the Pas du Callais area of France, before the French protestants were driven out of France by the Edict of Nants. So anyone today with the Boland name, they will most likely find that if they go back far enough it will lead to France. That is why the name Boland shows up in so many countries now.
As for your question. What I did was try to find where my great grandfather came from, which I was lucky we have his Prussian Army passbook which listed where he was born. If you can find the name of a town/villiage, you may be able to look up and see if there are church records filmed for that town on this websitehttp://www.familysearch.org/Eng/Library/FHLC/frameset_fhlc.a
That is for the LDS Family History Center website, If the town's church books were filmed, they would have the copies there and they can be requested from a local Family History Center.
You could also, if you have a town name Google it and see if they have a webiste for that town or area of Germany that may give you more information about the area.
Hope some of this helps. If not feel free to email me and I can see what I can do to help you further
