Trying to help a guy trace his grandfather who served in the 10th . Only info he has is - his grandfather married Gertrude Selle in 1950 in Iserlohn . Not sure if he even knows the name of his grandfather . Just thought there may have been a record of serving men’s marriages in 1950 ? He’s trying to find family because of some kind of medical thing . I’d be grateful if anyone can throw any light on this please - or advise how he can proceed . Thank you .
