I simply don't know what more to do now. We are in a period, where it's difficult to find online records for the children etc. Could you perhaps scan and send me some of the letters with e.g. the name Gette (as I have never heard that name) - could be Gitte? - and other names.
Another thing you could do is to make a posting (with all details and what has been found) on http://www.slaegtsogdata.dkhttp://www.slaegtsogdata.dk, where many people are very willing to help. It might even be that somebody will know your family? You should post it on the English speaking forum. You will have to register as a user (= bruger) but it's free to use the site. Here you will find instructions in English: http://www.slaegtogdata.dk/andet/arkivalier-online-help/?searchterm=englishhttp://www.slaegtogdata.dk/andet/arkivalier-online-help/?searchterm=english
