Dieter,
There are good similarities between your data and mine. I am sending you a PDF file that contains all my data and supporting footnotes on Carl Klabunde's children and grandchildren. I have a different birth year for Emil; our records are consistent to the day on Albert Friedrick Wilhelm; and I was unaware of a Hermann or Martha.
Let's continue our dialogue. I would love to determine more facts of Carl Klabunde (1816), and his parents, and further confirm my current data.
