I found an excellent website/forum last week.
There is a lively discussion about Lillian Alling and about other adventurers/travellers of the 1920s and 1930s.
To go directly to the page that discusses Lillian, go to:http://forum.poehali.net/index.php?board=7;action=display;threadid=20820
and scroll down to the bottom of the page for the latest entries.
The site is written in Russian, but can easily be translated using Google language tools.
Thanks to Aliaksandr for the great information and conversation via email, and for the link to his site.
