I am trying to find out who these 4 siblings are. They seem to be relatives to us but all I know is that they lived in Tallin / Reval. No names. I also have another picture of them taken few years later were they are by an old huge oaktree. https://www.dropbox.com/s/u0ychsc1ijis9j6/Reval%2Crelatives...
