Hello,
do you mean this person:
Zeindl, Johannes
(war cemetery in Lübeck-Travemünder Allee, Block VI Reihe R Grab 28) - source:
www.volksbund.de, Gräbersuche online. There is no more information on this Zeindl.
The only NSGr.-related unit that was in Lübeck at that time (April 1945) must have been 15./SG 151 (Nachtschlacht replacement & training unit, Ju 87). Although parts should have been in Grossenbrode (62km east of Kiel) at least until 26 April 1945.
Do you have additional information on Zeindl´s fate: such as information on his last flight, which type of plane, name of pilot, etc.
You may make contact with me offline under
info@nachtschlacht.de
Greetings,
Dr. Christian Möller
