Looking for date and place of birth

[rob van den nieuwendijk]

Hello,

I am looking for the date of birth of the following two pilots of II./JG 3:

Unteroffizier Rudolf Stephan of the 5./JG 3 - he was killed on 11.04.44 near Braunschweig

and

Unteroffizier Johann Fröhlich of the 5./JG 3 - he was killed on 24.05.44 near Neustrelitz.

Thanks!

Best wishes,
Rob

PS
Was unable to locate these German airmen on the site of the Volksbund
