John Rosenkrantz - Boston, Mass, 1869
I am looking for information on a John Rosenkrantz who filed a patent with the United States Patent Office in 1869. I have a copy of the patent, but how I got to that point is a long story. The patent lists him "of Boston, Massachesetts". I don't know if he is relation or not, but I'm quite curious.. if anyone has information, I'd appreciate an email to [email protected]
