Thank you for responding, Jetti. Per the letter he wrote in June 1937 he said:
This is the first letter from you correspondent and no less than a Dutch
boy namend Hermannes Roelofs, Stieltjeskannaalen, Dalen Drente, Netherland.
Your correspondent is born on the twenty fourth of July 1919 and is the son of a
farmer, he is studying at a seminary for teachers of Koevorden (sp).
Unfortunately, I do not know the name of his wife. If you would like to see the letters which might have clues in them you can find them on the following website:http://www.laurahavran.com/parkys-pen-pals.html
