Re: Seeking any and all information on Max Koenig and Hannah (Morgenstern)Koenig #usa
You can see a transcription of some death cert info at:
Seeing spouse and parent's names will help determining if one of these is who you seek.
The only one on your list with a spouse named Anna is Max Konick age 84 died in kings 4/23/1945 #8594.
I did not find the death cert for Anna in 1948 to be listed in this database.
