Franz,
The
www.volksbund.de website says that the body of Heino von Davier could not be traced, so no burial has followed at the Hunkovce Sammelfriedhof (Slovakia).
Therefore only his name is written in the memorial book of this cemetery.
Website gives Vajkovice as place of death or where he went missing.
He was born on 1.1.1921 at Neumünster.
Regards,
Leendert
