I have 2 Fred Rotes in Lancaster, PA. The father, John Frederick Rote, b. 1816 d. 1886 in Lancaster and went by the name Frederick. His son, Frederick A. Rote, b. 1852, was living "at home" in 1870 and was working as a photographer. I don't know what happened to him after that. If you wish to pursue this family, I have more info.
