The first letter is dated October 6th, 1938. The contents are of someone asking to be sent the birth and marriage certificates of an Adolf Weirauch born “around 1770-1780 in Nievenheim. The second letter is dated October 7th, 1938. The contents are of someone asking to be sent the birth certificate of an Wilhelmine Luise Latuske born on November 21st, 1913 in Düsseldorf. I haven’t found out what these were for specifically. But based on the contents it seems to be checking for someone’s heritage. Possibly to see if they had any Jewish ties etc.
