How to find living siblings of person born 1920?

[rostben]

I would like to find living siblings of my mothers (A) very good friend (E) born in 1920 in Denmark. I know her names and birthdate, and some adresses were she lived in Copenhagen. I also now the name and birthdate of her daughter (I) born in 1941 in Copenhagen. I do not currently know if E had more children. I do not know wether I is still living. I want to get in contact with I or her possible childrens. I have some fotos of E and of I in 1942. A and E wrote many letters to each other, during a 15 year period close to 200 each. I would like to see if the letters from A are preserved and how to be able to read them.
Many thanks for any help!
