I'm looking for relatives of my great grandfather, Gustav Paul Bensch - born 27 May 1890 in Kosendau (now Kozów) - near Goldberg (now Zlotoryja). He went by his middle name, Paul. He was married (don't know her name) and living in Jauer (now Jawor) in 1929. He visited the U.S. in 1929 for an unknown reason and when he returned in 1933, his family was gone. Paul came back to the U.S. and remarried. He had a son, my still-alive grandpa, and I would love to find out if he has half-siblings out there.
A researcher from Legnica tracked down the birth certificate for Gustav Paul Bensch. His parents were listed as Wilhelm Bensch and Ernestine Zingel and they were evangelical. The researcher looked for birth records of siblings in the Legnica archive, but did not find any. My family does believe there were several brothers though.
Any information would be appreciated!
