Hi Michael,
Here is the source info for the Stab:
Stab/SG 1
………..
7 Feb 45: withdrew to Hexengrund/8 km NNW of Gdingen (Gdynia).
M.Holm-op cit.
1 Mar 45: now at Oranienburg/25 km NW of Berlin (1. Fliegerdivision).
AFHRA Maxwell: decimal 512 (British Air Ministry) German document Ia Nr. 280/45.
29 Mar 45: Fürstenwalde/50 km ESE of Berlin engaged against the Oder bridgeheads under 4. Fliegerdivision/Luftflotte 6.

As you can see, the two from March come from original Luftwaffe documents.
Every little bit helps!
