Werner,
There is a Bernhard Brankamp, age 7, born in Germany living in the 10th ward of Cincinnati, OH in 1850 with Bernhard and Elizabeth Von Handorf and their children Bernhard (age 9) and Augustus (age 1). Everyone was born in Germany except for Augustus. That is the only name that I could find that was near you Bernard but this one would not have even been born in 1841 come to think of it. Sorry.
