I have a fairly full document set on my gr grand Herman Schroeder who was born in Lamstedt in 1848 and gr grand Marie Woelber who was born in Bulkau in 1854. They migrated separately to NY ca. 1870. They had strong association with Evangelical Lutheran Church in Brooklyn... and death certs for Herman and his brother name the parents.

All of that would bode well for a successful research project. So. I'm looking for suggestions/recommendations for a good Hanover researcher in Germany.

Thanks in advance.
