possibly related - Two Kroll brothers in Germany. One opened the opera house along with the beer gardens, and the other came to USA. The one who left Germany was a carriage maker from Stuttgart. He opened a carriage making shop on Broad Street in Philadelphia, Penna. In fact, after his death, the body of Pres.Abraham Lincoln was transported in a funeral hearse built by Kroll in Philadelphia. I am not sure of the names, but I was under the impression that somehow krolls went to Australia. My daughter did a lot of research on Kroll family some years ago.If you wish to continue, I would like to establish that we are talking of the same family. How and when did your ancestors get to Australia?
