I have a HANS FRANK DITTRICH in my WINKLER line. he was born August 27,1883, Leipzig, Germany. He married my grandfather's sister/niece, Lydia Winkler. I think he came to the US about 1910 He attended Zweite Stadtische Fortbildungsschule fur Knaben zu Leipzig (school for boys in Leipzig) in 1900. I have papers that look like his mother was Martha Sittig(?) I found his children and have spoken to both of them on the phone. Does this help any DITTRICHS' ???
