one of the places where descendents of a Janus-family came from is Jaschkowitz, some km north of Pitschen in the area of Creuzburg resp. Oppeln (today in polish Opole). An other branch came from Polanowitz not far from Jaschkowitz. One guy of one of these huge families was Daniel Janus, born 1821. He was the oldest son of Thomas Janus and had 9 brothers and sisters. Daniel had a son: Carl Gottlieb Janus, and Carl Gottlieb had two sons: Carl and Paul. And Paul is my grandfather. Is there somebody who has an idea of these names or locations?
